Different M.Tech courses or branches with high job opportunities related to ece in india

1 comment
mtech admissions
Job opportunities are more for VLSI,Embedded, Communications, Computer science and signal processing branches in reputed colleges like IIT’s,NIT’s and Top universities.
So,According to my opinion its better to take any of the five branches. Here I am not saying that the remaining branches have no job opportunities but when compared to the above five branches remaining branches have less opportunities. 

So,Try to get admission in any five course in reputed college, for that you need to get a good score in GATE exam. If you didn’t get any of the five branches don’t worry whatever branch your studying perform well in that branch then there is a chance of getting good job.

Different ECE M.Tech Branches

1. Digital Electronics & Communication
2. Signal Processing

Plan your career to get a job in electronics core company

No comments
We are all electronics engineers looking for a job in core company, here I am giving some suggestions to get a core job based on my experience. we know that there are two core sectors one is private and second one is a government sector, you should decide which one we have to choose. If you choose a private sector the preparation will be little bit different than government sector.
  • Most of the government sector companies will recruit talented candidates based on the GATE score, I already discussed and posted the list of companies which are recruiting purely based on GATE score, Now I am discussing about the companies which are recruiting through the written test conducted by them.
  • The written test will consists of Technical(GATE/IES preparation is enough), General English,General aptitude and General awareness. so, you should clear knowledge on both technical and non technical concepts.
  • Now the private sector : In case you have companies visiting your campus , GATE /IES preparation would be enough for you to get through the technical written exams and for non technical: Aptitude,English and basic programming languages.
  • For interviews one can focus on the Projects and Internships. Though preparing all this can help you in the interview it would be advisable that you begin to revise your course subjects from the very start of your final year. This would help you clear your concepts and that is really important.
  • In case the core companies do not visit campus then make sure that you properly utilize your internships and projects and apply in companies that work in similar domains.
  • We gave some core companies list, so you can post your resume through the carrier links provided.
  • The following skills are must for private companies
    1. C Programming - Must
    2. C Language - Basics
    3. Data structures

The Best Career Options for EC Engineers in VLSI Companies

 Electronics and Communication is considered one of the toughest engineering branches. However, the rewards that it offers in terms of some of the most challenging and exciting careers make studying this branch totally worth it. VLSI or Very Large Scale Integration also sometimes known as Chip design is one of the sub-domains of electronics, dealing with the particular logic and circuit design techniques required to design integrated circuits.
      There are numerous good opportunities for individuals after completing B.Tech in ECE. One can resort to private companies which offer competitive salaries, ample opportunities to learn and an exciting career path. On the other hand, public sector companies also have a number of great opportunities that one can pursue in the electronics. However, if you want a job in the government sector then there are other additional requirements such as clearing the entrance exam conducted by Union Public Service Commission or State Public Service Commission. Out of so many subsets of Electronics and Communication Engineering, VLSI holds special importance as it has some of the highest paying careers for professionals.

clip_image001What is VLSI?
VLSI or Very Large Scale Integration is all about Integrated Design. In layman’s language it is known as chip design. This is a highly technical field which requires complete understanding of complex semiconductor concepts. VLSI design is mainly treated as hardware design as one is required to define the chip’s architecture, create circuit designs, run simulations, tape out the chip to the foundry and test the prototype once the chip returns from the laboratory. Individuals who are creative and try something more challenging than the jobs out there should look for jobs in VLSI. You will need good programming skills along with excellent mathematical and analytical aptitude. Expertise in high level languages such as Verilog and VHDL, which are probably the most popular languages in chip designing, is one of the important criterions of getting selected for a job in VLSI.
Industry news
        These are the times of wearable technology. Even clothes have chips inside them. Then there are the electronic appliances that we simply can’t think of even living without such as microwave ovens, air conditioners, mobile phones, televisions and others. There is little doubt over the bright future of chip designers and programmers and therefore, making a career in this field can be of huge advantage. VLSI engineers can work in wide variety of industries such as Telecommunication, consumer electronics, semiconductor, embedded systems amongst others. These engineering jobs are also the best paid employment opportunities in India.
Different Types of Job Opportunities
One can differentiate between different types of jobs in VLSI by either the industry or the work responsibilities. Going by the kind of work, there are mainly four types of jobs:

Design Engineer
          A design engineer, also known as physical design engineer is mainly responsible for design implementation. One needs to be technically sound to efficiently deliver the work responsibilities. One deals with different kinds of chip designs such as ASIC, FPGA, DFT, AMS, PCB and other custom designs. The various job titles that are assumed by professionals handling all this work include PCB designer, Back-end designer, Front-end designer, AMS designer, DFT designer and Library developer.
Verification Engineer
        As the name suggests, verification engineer verifies the design and makes sure that it works fine. India is known for its world class verification facilities and around 70% of projects here are related to verification. Therefore, the demand for verification engineers is maximum in India. To make it big in this field one needs to have strong programming skills. The different types of verifications undertaken by professionals include front-end verification, acceleration, product validation, behavioral modeling, and Verification IP implementation. Modeling engineers, Validation engineers, verification consultants all have similar responsibilities.
Application Engineer
       An application engineer is responsible for creating the interface between the R&D and customers and promoting EDA solution. In order to effectively carry out these responsibilities, an application engineer should have good communication and interpersonal skills. With excellent presentation abilities one can go places under this job title. Field Application Engineer and Corporate Application Engineer are some of the job titles in this field.
There is a huge potential in the market for those interested in VLSI. The demand of chip designers is higher than the supply, which means the existing roles are highly paid as well, a win-win situation for VLSI engineers.

Materials used to made a CPU Processor

No comments
Recently, Intel has published a page showing the step-by-step process of how a CPU is made. From sand to its final product, there are many complex steps involved. In fact, it’s absolutely amazing that semiconductor products work at all.
Step 1 – Sand
At about 25% (by mass), silicon is the second most frequent chemical in the earth’s crust (behind oxygen). Sand has a high percentage of Silicon Dioxide (SiO2), which is the base ingredient for semiconductor manufacturing.
Step 2 – Melted Silicon
Silicon is purified in multiple steps to reach the Electronic Grade Silicon used in semiconductors. It ultimately arrives in mono crystal ingots about 12″ in diameter (300mm today, the older ingots were 8″ or 200mm in diameter and smaller — the first wafers in the 1970s were 2″ in diameter, or 50mm).
The purity at this level of refinement is about one part per billion, meaning only one foreign atom per billion silicon atoms. The ingot weighs about 220lbs, and is a 99.9999% pure vertical column of slick glass-looking material.
cpu_step2Step 3 – Ingot Slicing
The ingot is cut with a very thin saw into individual silicon slices (called wafers), each of which are then polished to a flawless mirror-smooth surface. It is upon this totally smooth wafer surface that the tiny copper wires are deposited in the following several steps.
cpu_step3Step 4 – Photo Resist, Exposure
A photo resist liquid is poured onto the wafer while it spins at high speed (similar to materials used in conventional photography). This spinning deposits a thin and even resist layer across the entire surface.
From there, an ultraviolet laser is shone through masks and a lens (which make a focused image 4x smaller than the mask) causing tiny illuminated UV lines on the surface. Everywhere these lines strike the resist, a chemical reaction takes place making those portions soluble.
cpu_step4Step 5 – Washing, etching
The soluble photo resist material is then completely dissolved by a chemical solvent. From there, an etching chemical is used to partially dissolve (or etch) away a tiny quantity of the polished semiconductor material (the substrate). Finally, the remainder of the photo resist material is removed through a similar washing process, revealing the etched surface of the wafer.
cpu_step5Step 6 – Building up layers
In order to create the tiny copper wires which ultimately convey electricity to/from the chip’s various connectors, additional photo resists are added, exposed and washed. Next, a process called ion implantation is used to dope and protect locations where copper ions are deposited from a copper sulfate solution in a process called electroplating.
cpu_step6At various stages during these processes, additional materials are added, exposed, washed / etched and polished. This process is repeated six times for six-layer processes, which is reportedly what Intel uses for their current 45nm high-k, metal gate processes.
The final product looks like a jungle gym, a a host of tiny copper bars which convey electricity. Some of these are connected, some are exactly a specific distance away from other ones. And all of them are used for one purpose: To convey electrons, wielding their electromagnetic effects in a particular way to conduct what we would call “useful work” (such as adding two numbers together at extremely high rates of speed, the very essence of modern day computing).
This multi-layer process is repeated at every single spot on the surface of the entire wafer where chips can be made. This includes even those areas which are partially off the edge of the wafer. Why waste that space? It’s because the early chip makers learned that if they did not fill in these areas with (obviously) wasted semiconductor material, that the chips nearby also had a higher failure rate.
cpu_step8Step 7 – Testing
Once all of the metal layers are built up, and the circuits (transistors) are all created, it’s time for testing. A device with lots of prongs sits down on top of the chip, attaching microscopic leads to the chip’s surface. Each lead completes an electrical connection within the chip, simulating how it would operate in final form once packaged into end-consumer products.
A series of test signals are sent to the chip with whatever the results are being read. This level of testing includes not only traditional computational abilities, but also internal diagnostics along with voltage readings, cascade sequences (does data flow through as it should), etc. And however the chip responds as a result of this testing, is what’s stored in a database assigned specifically for that die.
This process is repeated for every die on the entire wafer’s surface while all dies are still on the surface.
Step 8 – Slicing
A tiny diamond-tipped saw is used to cut the silicon wafer into its various dies. The database derived in Step 7 is used to determine which chips cut from the wafer are kept, and which are discarded. The ones which produced “the right results” in Step 7’s testing are kept, with the rest being thrown away.
cpu_step9Step 9 – Packaging
At this point, all working dies get put into a physical package. It’s important to note that while they’ve had preliminary tested and were found to operate correctly, this doesn’t mean they’re good CPUs.
The physical packaging process involves placing the silicon die onto a green substrate material, to which tiny gold leads are connected to the chip’s pins or ball grid array, which show through the bottom side of the package. On the top of that, a heat spreader is introduced. This appears as the metal package on top of a chip. When finished, the CPU looks like a traditional package end-consumers buy.
Note: The metal heat spreader is a crucial component on modern high-speed semiconductors. In the past, a ceramic top was used with no active cooling. It wasn’t until the 80386 and later time frame, along with some extreme high-speed 8086 and 80286 (100MHz models), that active cooling was required. Prior to that, the chips had so few transistors (the original 8086 had 29K, today’s CPUs have 100s of millions) that they didn’t generate enough heat to require active cooling. To separate themselves, these later ceramic chips were stamped with the warning: “Heatsink required”.
Modern CPUs generate enough heat to melt themselves in a few seconds. Only by having the heat spreader connected to a large heat sink (and fan) can they operate long-term as they do.
cpu_stepfStep 10 – Binning
At this point the package looks like you or I will buy it. Still, there is one more step involved. This final step is called binning.
In this process, the actual characteristics of this particular CPU is measured. Items such as voltage, frequency, performance, heat generation and other internal operational characteristics of its cache, for example, are all measured.
The best chips are generally binned as higher-end parts, being sold as not only the fastest parts with their full caches enabled, but also the low-voltage and ultra low-voltage models. Note: Based on market demand, these highest-end chips can also be sold as lesser chip parts.
Chips which do not perform as well as the best chips are often sold for lower clock speed models, or as a triple- or dual-core (Phenom X3, Phenom X2) instead of their native quad-core. Others may have half their cache disabled (Celeron), etc.
wafer_yieldPerformance and Operational Yields
The process of binning ultimately determines the final yield at given speeds, voltages and thermal characteristics. For example, on a standard wafer only 5% of the chips produced might operate at the highest-end clock rate of 3.2GHz. However, 50% may operate at 2.8GHz.
While this performance yield does not relate to operational yield, it is equally as important to manufacturers as they are constantly looking to determine the reasons why one CPU might operate at 2.8GHz without issue, but not faster, while another operates at 3.2GHz. As the cause of this discrepancy is determined, sometimes the chip’s very design can be updated to increase the performance yield (and operational yields).

ISRO previous year question papers for electronics and commnications(ECE)


Indian space research organisation is one the center to study about the space.ISRO (Indian Space Research Organization) is to develop space technology and its application to various tasks of national and international interest.
every year they release a notification to recruit a young scientist. So to Get clear the written exam you must start preparation from now onwards.The exam paper will totally objective with negative marking,the syllabus is totally similar to GATE syllabus but some questions will also come from basic computers.

The cutoff for the written exam will changes for every year, But approximately if you get 150 marks then there is a chance of getting call for Interview.

How to prepare to the ISRO written exam:

The exam question will be like a GATE model questions.So be thorough with all the topics and practice all last 10 previous ISRO ,GATE, IES papers.No need to study in depth concepts to clear written exam because there is a less time to study so, practice all previous questions of GATE, IES, ISRO and try yourself to get the solutions to the previous questions. I  think previous question is enough to clear written exam but the chance of Repetition of the questions is very less, they may ask similar models as in previous questions so, practice all the questions clearly.

Mainly concentrate more on weightage subjects like ANALOG CIRCUITS, DIGITAL ELECTRONICS, ELECTROMAGNETIC FIELDS, COMMUNICATIONS,ANTENNA BASICS.  their is a chance of getting more questions from these subjects.

ISRO syllabus for electronics and communication(ECE)

No comments
ISRO Scientist-B recruitment exam syllabus 2017:
The syllabus is similar to ECE GATE syllabus,we should prefer GATE and IES electronics syllabus for any competitive exams, In isro written exam some questions will be asked from computer engineering which is not in Gate syllabus, here I am giving basic syllabus based on previous papers,You can also see the previous isro papers here.

(1) Electronic Devices and ICs:      
Energy bands in silicon, intrinsic and extrinsic silicon. Carrier transport in
silicon: diffusion current, drift current, mobility, and resistivity. Generation and recombination of carriers. p-n junction diode, Zener diode, tunnel diode, BJT, JFET, MOS capacitor, MOSFET, LED, p-I-n and avalanche photodiode, integrated circuits fabrication process, oxidation, diffusion, ion implantation, photolithography, n-tub, p-tub and twin-tub CMOS process.
Straightforward problems are only asked, which can be solved with basic concepts in diode, BJT, JFET and MOSFET(less important). Expect theory questions also from other topics. 

(2) Signals and Systems:
Classification of signals and systems; System modeling in terms of differential and difference equations; Fourier series; Fourier transforms and their application to system analysis; Laplace transforms and their application to system analysis; Convolution and superposition integrals and their applications; Z-transforms and their applications to the analysis and characterization of discrete time systems; Random signals and probability; Correlation functions; Spectral density; Response of linear system to random inputs.
(3) Network Theory:
Network analysis techniques; Network theorems, transient response, steady state sinusoidal response; Network graphs and their applications in network analysis; Tellegen's theorem. Two port networks; Z, Y, h and transmission parameters. Combination of two ports, analysis of common two ports.
(4) Electromagnetic Theory:
Analysis of electrostatic and magneto-static fields; Laplace's and Poisson's equations; Boundary value problems and their solutions; Maxwell's equations; application to wave propagation in bounded and unbounded media; Transmission lines: basic theory, standing waves, matching applications, Elements of antenna theory and microwave basics.

Expect majority questions from this topic. Study this topic really well, as many theory questions and problems are asked from this. Many questions from microwave is asked which is out of syllabus for gate. Study satellite communication link design and antenna theory also. Questions from topics which we don’t usually find important for GATE can come.
(5) Analog Electronic Circuits:
Transistor biasing and stabilization. Small signal analysis. Power amplifiers. Frequency. response. Wide banding techniques. Feedback amplifiers. Tuned amplifiers. Oscillators, Rectifiers and power supplies. Op Amp, 555 timer, PLL, other applications. Pulse shaping circuits and waveform generators.

Mainly circuits with BJT and OPAMPS only asked. Also learn Rectifiers with zener diode
(6) Digital Electronic Circuits:
Boolean algebra, simplification of Boolean function Karnaugh map and applications; IC Logic gates and their characteristics; IC logic families: DTL, TTL, ECL, NMOS, PMOS and CMOS gates and their comparison; Combinational logic circuits; Half adder, Full adder; Digital comparator; Multiplexer De-multiplexer; ROM and their applications. Flip-flops. R-S, J-K, D and T flip-tops; Different types of counters and registers. Waveform generators. A/D and D/A converters.

Lot of very straight forward questions asked. So brush up everything and study A/D converters which is not that important for gate.
(7) Control Systems:
Transient and steady state response of control systems; Effect of feedback on stability and sensitivity; Root locus techniques; Frequency response analysis. Concepts of gain and phase margins; Constant-M and Constant-N Nichol's Chart; Approximation of transient response from Constant-N Nichol's Chart; Approximation of transient response from closed loop frequency response; Design of Control Systems; Compensators; Industrial controllers.

Very few questions are asked, that too straight forward negative feedback question, system response etc. and related to concepts in root locus and other graphical methods
(8) Communication Systems:
Random signals and noise: probability, random variables, probability density
function, autocorrelation, power spectral density. Analog communication systems: amplitude and angle modulation and demodulation systems, spectral analysis of these operations, superheterodyne receivers; signal-to-noise ratio (SNR) calculations for amplitude modulation (AM) and frequency modulation (FM) for low noise conditions. Digital communication systems: pulse code modulation (PCM), differential pulse code modulation (DPCM), digital modulation schemes: amplitude, phase and frequency shift keying schemes (ASK, PSK, FSK), matched filter receivers, bandwidth consideration and probability of error calculations for these schemes. Basics of TDMA, FDMA and CDMA and GSM.

Compared to gate syllabus, this is having lot of advanced topics. Study each and every heading in this. Anything can be asked (mostly direct but expect little tricky questions here). Even questions from coding theory have been asked even though not in GATE syllabus.
(9) Computer Engineering:
Number Systems. Data representation; Programming; Elements of a high level programming language PASCAL/C; Use of basic data structures; Fundamentals of computer architecture; Processor design; Control unit design; Memory organization, I/o System Organization. Microprocessors: Architecture and instruction set of Microprocessor's 8085 and 8086, Assembly language Programming. Microprocessor Based system design: typical examples. Personal computers and their typical uses.

This topic you will find difficult to study, as it is not for GATE and from previous year paper it is not easy for pin pointing even the correct syllabus. Many topics electronics students are not studying(mostly computer science people only knows the answers so get their help in finding answers in the previous year papers). Better don’t waste too much time in this. Study only basic concepts in computer networks, computer organization and microprocessor (study if you have done it as part of university syllabus and leave the more advanced topics in this and devote more time on to gate syllabus part)

Know about wearable devices technology

1 comment
Wearable devices are miniature electronic devices and their market is expanding at high rate. There are many examples of "wearables¨ available today. For example, smart glasses, ear buds, headphones, smart clothing, smart watches, fitness bands, smart jewellery. Mobile Wearable technologies is the pioneer and worldwide leading innovation and market development platform for technologies worn close to the body, on the body or even in the body. Thus, all types of "wearables" are portable however they are also related to the cloud-based services that take the data from the devices and return analytics and insights to benefit the user.
While designing wearable technologies factors to be considered are as follows:
  •  Power. Power consumption is a critical design requirement and thus a challenge in "wearables". Battery power in "wearables" is expected to last for a significant amount of time.
  •  Connectivity. "Wearables" require connection with other devices via wireless connectivity. Wireless protocols are Wi-Fi, Bluetooth Low Energy, IEEE 802.15.4. Many times wearable devices support more than one wireless protocol.
  • Size. Technology is becoming more and more versatile along with decreasing its size; such technology also attracts the market. Same is the case with wearable devices i.e very powerful functions are to be packed into a very small space. As they need to be compact, a small touchscreen with gesture detection capabilities is carried on wearable electronic. The touchscreen can be capacitive, resistive, surface acoustic wave, and optical imaging.
  •  Aesthetics. While maintaining size and functions, best wearable devices also need to be stylish and fashionable and blend well with other ornaments.
  •  Tolerance. Based on the type of wearable device, tolerance of heat, water and vibrations becomes a necessity. For example, smart watches need to be tolerant to water and same is expected from fitness bands.
Google Glass is one of the most publicized wearable electronic device. Google glass is a pair of glasses to wear that has a mini display screen which can be seen in the corner of vision. There is a touch pad on the side of the glasses which can be used to access information and a camera to capture activities going on in front. It also has a microphone, so voice recognition can be used to type messages or to send commands, same as Apple's Siri or Google's version of Siri, called Google Now.

The wearable market grows more and more as the interaction between watches, phones, glasses, headsets, and clothing increases. So, with more devices in the market each day, developers are needed to build applications for these devices. Wearable devices will change the way applications are designed and developed. For example, Google's Android Wear is an Android platform that will help developers build apps that work on the various wearable devices.
Wearable technologies are used in almost all fields, such as follows:
  • Sports and Fitness. Tracking performance is increasingly important for athletes to get qualified input about vital data during workouts. Wearables devices make such measurements smooth and unobstructive. Some "wearables" widely in use in this category are GPS watches, heart rate monitors and pedometers.
  • Healthcare and wellness. Remote patient monitoring has become possible. Wearable medical devices give patient freedom to move around as they like. 
  •  Security and prevention. Wearable Technologies are used to ensure highest, up-to-date safety and security standards. For example, special lighting technologies for better visibility, home security systems, protective clothing and special gear for extreme sports, rescue teams, workers, or tracking devices for a healthy lifestyle.
  • Gaming and lifestyle. World of gaming is undergoing huge changes, and the "Wearables" are playing a massive role in it.
