The scope of VLSI – Is one of abundant opportunities. There is a constant rise in the demand for VLSI Design Engineers but very few opt for the career option! 

“According to industry experts, the Indian VLSI industry requires anywhere between 10,000 and 20,000 highly trained engineers at present. According to a joint report of India Semiconductor Association (ISA) and Ernst & Young, the semiconductor design industry in India is expected to log a compound annual growth rate of 17.3 per cent over the next three years to reach $10.6 billion…” – Electronicsforu.com 

To survive in a growing industry you need to acquire the right skills and aptitude with a desire to learn while you work. Since this deals with the latest technologies that are ever changing, keeping up with the market might become tedious if it is not your passion. Some of the major organizations that require VLSI Engineers are: HCL, Intel, Micron Tech, Motorola, Philips Semiconductor, Wipro, TCS and many more. 

When these companies hire VLSI Design Engineers they are primarily looking for fundamentally strong individuals with expertise in electronics and knowledge in system design, timing and semiconductor physics. You need to be strong when it comes to languages like VHDL, Verilog, Spec-man and System Verilog along with skills to program and script.  

Surinder Bhagat, country HR manager, Freescale Semiconductor India, says, “We prefer an educational back-ground of BE/B. Tech, ME/M. Tech or PhD with specialization in electronics, telecommunications, electrical or VLSI domain. Typically, these professionals should have hands-on experience in systems design, digital ASIC design, physical design, mixed-signal IC design, VHDL or very high-speed integrated circuit, VLSI design, circuit design and simulations, microcontrollers, digital PCB design and routing.” - Electronicsforu.com

Professionals say, since there is a constant growth in the industry with shortage of resources, it is the right time to enter the market with ample opportunities. 

According to the director of VEDA IIT Dr. Subbarangaiah, 

“Even though around 250,000 engineers are graduating in electronics and other related streams every year, less than 3 per cent of them are equipped with the knowledge and skills needed for the VLSI industry.”- Electronicsforu.com

Understanding the complexities of VLSI Design and the need for more young students to take it up as a career option propels the need for Engineering Colleges to provide ME in VLSI Design. These institutes should be well equipped with technological libraries, design manuals, design flows and industry standard tools for practical studies. Technical knowledge or work experience in nano-technology will also be helpful.

Engineers who build strong domain knowledge and have sufficient fundamental knowledge of circuit, design, verification are given higher priority over the ones without. 

Hence, it is beyond doubt that innovation and technology are rapidly growing and need for VLSI is growing at par; this industry has grown over the last three years from SSI (Small-scale Integration), MSI (Medium- scale Integration), LSI (Large-scale Integration) to its current VLSI. The next to look forward to is nanometer designs! 

Know your business needs for data processing

Data processing as the name suggests, is putting together and manipulating data to produce meaningful information. The term is more used for business or commercial organization, to refer to some class of data processing applications. The right combination of data processing is specific to each business, and establishing the right mix is essential. Both automated and manual data processing has its pros and cons and which need to be taken care duly. As the name suggests, manual data processing is the traditional method which make use of pen, paper, chalk requires human effort for recording, sorting, and processing of data which can be boring, tedious, time consuming and more chances of human error.

And automated processing of data is use of electronic systems, programs in which data is fed and retrieved after being processed. Some of the examples of automated data systems are recognition technology and manual data processing. The accuracy of automated systems have been questioned since the technology was first introduced, the performance of a system is determined by information which is 100% correctly processed at a specified amount of time. Manual keying, is also not error-proof and hence the baseline of comparison.

Recognition technology does not face problems of human factor, but the performance depends on issues, such as application, quality of images etc. It is important to understand the application and its limitations for best results. Optimal Character recognition, and intelligent character recognition are for high levels of accuracy when working with texts such as boxes, lines and combs. A high quality machine print can give nearly 99.9% accuracy which is high enough to be used without additional controls. But the level of accuracy can differ with machine font.

Although manual data processing has been in use for millennia, the term has been used more since the 1950s. For example, book keeping for an organization involves report making such as balance sheets and cash flow management, and posting transactions. The methods which were completely manual were augmented with the use of mechanical or electronic devices. The person which performed functions of calculation manually or by using a device was called “computer”.

Because manual data processing was tedious, required much longer duration of time for processing complex data automatic data processing evolved. The term automatic data processing was used for operations, which were performed by means of unit record equipment that used applications such as Herman Hollerith’s application for punch card which was used in the 1890 United States Census. Computerized or electronics data processing further represents evolution, in which the computer replaced several pieces of equipment.

The term “data processing” is subsumed in the new usage of Information Technology instead. In the new context, data processing refers to use of older technologies and a negative connotation is associated with the same. In commercial data processing, the volume of data is large with less computation operations and large volume of output. In science and engineering, data processing and Information processing are too broad to be used, the term “data analysis” is used instead. Data analysis makes use of accurate algorithms and statistical calculations which are not observed in typical business environments.

Of all the advantages of automated data processing over manual is, it can process and forms and documents quickly and efficiently. The software recognizes the characters on the form, which can be transferred to electronic format. The accuracy of automated systems ensures, data is rightly extracted and used in the correct field. This helps employees, use their competencies in other capacities instead pore over forms for repetitive data entry.

UK and American countries import maximum software from the IT giants of India like Infosys, TCS, Cognizant, L&T Infotech, Tech Mahindra, Satyam, Wipro etc. The demand and supply of software is never ending. The scope of engineering in Computer Science finds potential demands for the role of Programmer Analyst, Research and Development official, Computer Auditor, Artificial Intelligence analyst, Systems engineer etc. 

The role of database is quintessential in every field of work. Every field requires a robust database to save the data of thousands of people and work done. Such a process can never be done with the traditional file systems which are cumbersome and complex. To make the task easier, the relational database is required accompanied with queries for effective manipulation, insertion and updating of data at required time intervals. The flat file approach used few years back is now obsolete. They are replaced with newer mechanisms. This field of computers in engineering will never go out of scope as effective maintenance of data is essential.

To become accomplished as an effective Software engineer, top engineering colleges in India play a major role. Few of the best IT engineering colleges in India likeMIT can help you to become a successful engineer in future.

Necessity of Filter capacitors in electronic circuits

 Are you wondering why there are so many capacitors scattered throughout the electronic board? What exactly is their purpose? Often, even the Top Engineering colleges India might skip explaining such simple concepts so we’re here to help. Here, in this article we will cover every detail from what is a filter capacitor to its uses and importance in an electrical circuit. Firstly what is meant by filter capacitor? A filter capacitor is an electronic device that diminishes the voltage and signal ripples from electronic circuits. Capacitors with an ability to absorb and efficiently control the electrical charges at predetermined values are used as filter devices. This feature of the capacitor is basically used in a filter capacitor application is to absorb or monitor the voltage frequencies that exceed the required figure.

A filter capacitor performs various functions in the electric and electronic field. The numbers of applications covered by this device are as follows:

• Filter capacitors are used in almost all sorts of filters that are used in signal processing. It works as a filter in an audio equalizer, which uses several frequency bands so as to allow different amounts of amplification for bass, midrange and high frequency tones.

• It removes Glitches on Direct current (DC) power rails.

• It also helps in the removal of Radio frequency interference (RFI) for signal or power lines entering or leaving equipment smoothly.

• The Filter Capacitors are used to further smooth dc power supplies after a voltage regulator.

• It is also used for Arc suppression, such as across the contact breaker or 'points' in a spark-ignition engine

These filter capacitors are available in many materials from mica capacitors, ceramic capacitors and tantalum capacitors to aluminum electrolytic capacitors, paper capacitors and so forth. Each of the material has its own importance and purpose. Some of the uses of different types of materials are as follows:

• Electrolytic capacitors are mostly used for its high capacity at low cost and low size.

• Ceramic plate capacitors owing to its extremely low inductance and low cost are mostly favoured.

• For the purpose of precision, silver mica capacitors is used. It offers superior precision and stability.

• Plastic film trimmers are basically used for the purpose of manual tuning, though for some time now it is popular to adjust the inductor to achieve tuning.

• Disc and plate ceramic capacitors are usually used owing to its particularly low inductance.

It is very important to know the right positioning of this device for its effectiveness. A filter capacitor is usually placed across a load or connected in a way so as to offer a monitored path to ground. In this placement, the capacitor is able to absorb any voltage above its set parameters in a most effective way.
Now we arrive at a very important question of what is the importance of these filter capacitors in electric circuit. A biggest problem faced by electronic circuit designers is the removal of voltage and signal glitches. It may occur in the form of either DC ripple in power supply outputs, audio interference, or switch induced arcing. These deviations can create havoc however the capacitor's ability to absorb and hold electric charges at a pre set value makes it an ideal filter component to be used in electric circuits.

Laser Diodes, their Application and Study

A laser diode, also known as a diode laser, is a semiconductor device that emits light radiation which is coherent. Laser diodes generate a beam of high intensity light and are also referred to as injection lasers.

Though laser diodes are similar to the light emitting devices (LED), they are different from the other types of lasers, such as Helium-Neon and gas lasers. The weight of laser diodes is typically a fraction of a gram, therefore, they are suitable to be used in portable electronic equipments. Furthermore, the power requirements of laser diodes are very less as compared to the conventional lasers. As the laser diodes consume less power, they can operate even when there is a very little battery power supply. You can also easily switch the laser diodes on and off at high frequencies, due to which laser diodes can be used in high-speed telecommunication applications. Since laser diodes are small in size and made of semiconductor materials, they can be easily used in places where other types of lasers cannot be used.

Due to their continual advancement and developments, laser diodes are today available in shorter wavelengths and can produce an increased output power. Following are some of the different types of laser diodes available:

1.  Surface emitting laser diode: In this kind of laser diode, light emits in a direction that is perpendicular to the wafer surface of the semiconductor chip. This is a new type of laser diode.

2.  High power laser diode: It produces a high intensity power beam and is pretty small in size. The power requirements of high power laser diodes are very less.

3.  Index guided laser diode: It reduces astigmatism in single-mode output beams that it generates.

4.  Gain guided laser: It is the simplest kind of laser diode which uses a mechanism to control the spread of the laser beam.

From data recording and storage to optical fiber communications, high-speed telecommunication, dermatological therapies to remote optical sensing and blood analysis, laser diodes are today used across a wide range of industries.

Considering the wide range of areas that laser diodes can be used in, the study of laser diodes is a sought after course these days. MIT Academy of Engineering is one of the best engineering colleges Pune that offers the course for the study of laser diodes. MIT is a trusted name when it comes to imparting education.
