Therefore to overcome these tradeoffs silicon mentor working on many PhD thesis and VLSI project to get or innovate a new idea. So come and make a contribution for the development of society and add value to your research.

SiliconMentor: Revealing the Story behind its existence

SiliconMentor is a group of young entrepreneurs pledged to innovate in the field of VLSI by instantaneous interpositions in the technology. It was started in way back July 2013. 

Every start up has its own unique story and some key factors that drove them to start their setup and so is behind the existence of SiliconMentor. SiliconMentor emerged with an idea of two brainstorming VLSI engineers straying to find an opportunity to apply their skills both in terms of technology and its commercialization.

Having started in a box like structure as their workspace, their goals and visions changed at every step as they, themselves did not know about their forthcoming journey. Both of them had mesmerizing ideas to give a challenge to the semiconductor industries and sustain in the core world of electronics. 

On the very first day they sat on their seats with a hope to connect themselves with the VLSI aspirants and provide a certified and conceptual training to the B.Tech and M.Tech students. However, they were hopeless before they got engaged in the first research project in VLSI and later the celebrations after the completion of the project were like Indians celebrate after a victory over Pakistan.

Meanwhile, this was the beginning only before they started to convince the people by promising themselves to be the best among all the VLSI engineers having their setups in the Delhi-NCR region of India.

As much as they earned, they spent to fulfill their desires and more than that with a belief in the saying that “Savers are those, who do not know the ways to earn more” and later the time turned its phase and the ball curtailed in their court.

They went on getting the research projects one after the another and became experts to detect and correct the several small as well as giant problems related to the VLSI circuits and architectures. 

As the time snoozed off, so their goal jerked. Ideas were revolving around to become the most innovative research entity in the field of semiconductor but, the path was still in a haze. 

It is often said that “there is a delay but not the denial” and it completely applied on both of them because they delayed the delivery of work but never anticipated the students to a wrong path.

Semiconductor industry demanded mammoth money in the pocket along with the talent in the mind. The talent they had was not enough to traverse the VLSI world. 

Unlike the western governments, Indian government hardly supports the research activities which was also a discouragement for them and still a milestone to cover up.

PhD Thesis in VLSI

Doctor of philosophy is the final degree in any area. It requires a lot of efforts and hard work to achieve this. It starts with selection of a topic which should be recent and lies in your area of interest. If we talk specifically about research in technology then the next step is not straightforward and as simple as studying, collecting data, analyzing and writing the hypothesis. Research in technology requires implementation of work in the form of prototype or actual real time implementation of the idea.

If we narrow down our discussion to research in areas like electronics, electrical, computer science, artificial intelligence , wireless communication and related fields, which are the base of everything in this high-tech world. In these fields researchers have developed applications (aided with technology) for every field ranging from biomedical to aerospace and construction, which were nowhere related to electronics or even current.

As the research fields we are talking about are providing base to the developing world and providing it with reliable technologies which are being used in real time, the work of researcher becomes more wide starting with an idea to the realization of the idea in the real world in form of application or product.

To make a reliable and working model the idea of the VLSI design project ( i.e speech processing application, biomedical monitoring system etc) needs to be implemented and re-implemented, re-tested and improvised. The there are many development cycles and techniques available which eases up the implementation like:

·         Behavioral simulation

·         Software based model

·         Hardware Implementation (ASIC)

·         Programmable hardware (FPGA)

·         Co-simulation

Behavioral simulation is used at initial phase and it is not appropriate for testing the real time behavior of the system in actual environment as it is more close to systems behavior in ideal environment. 

We can simulate the actual environment by using different software models (more like software models of channels used to test communication systems) but its capabilities are also limited to human capability to model the environmental conditions in mathematical equations and models. 

All of us are familiar with ASIC, their high performance and hardwired implementation. These are good for final implementation but not for intermediate stages of implementation and testing. Nothing is better than ASIC for real time testing of analog VLSI circuits. But for digital circuits and DSP applications we have a better option of FPGA (Field Programmable Gate Array). 

The hardware co-simulation is a good idea to test and monitor systems in real time. To get more details about PhD thesis in VLSI you can do online research or contact us.

Different type of Transistor Logic Circuits

Logic Circuits:

Logic circuits play a vital role in designing digital electronics circuits. A logic circuit generates desired output on the basis of inputs applied and on the basis of rules which the corresponding gate follows. Logic Circuits include devices such as multiplexers, registers, ALU’s and Microprocessors. All these devices are designed using gates and gates are designed using transistors.

There are four categories in logic families:

RTL (Resistor Transistor Logic): RTL which is the first member of this family is not available in monolithic form. Such type of digital circuits are built using resistor as an input network and transistors are used for performing switching function. Advantage of using RTL is the use of minimum number of transistors but disadvantage is power dissipation is high when transistors are switched on.

DTL (Diode Transistor Logic): DTL is commercially available IC in 53/73 series. This class of digital circuit is direct forebear of TTL and in this gating function is performed by diode and transistor is used to perform amplifying function.

TTL (Transistor Transistor Logic): TTL is designed using resistors and BJTs. In this, gating function and amplifying function are performed by using transistors.

ECL (Emitter Coupled Logic): ECL belongs to non saturated class of digital logic family. In this current is forced between two terminals of an emitter coupled pair so sometimes it is called as Current Steering logic (CSL), Current Mode Logic (CML), Current Switch Emitter-Follower (CSEF) logic.

COMPARISON:

·     There is a disadvantage of high power dissipation in RTL circuits when transistor is switched on because of which high current is to be supplied and heat is generated inside the circuit. So to overcome these problems TTL circuits with Totem-Pole output are used.

·      TTL circuits are developed to provide higher speed and lower power dissipation for optimization of design. A TTL circuit has simplified design in comparison to other members of logic families and has high speed in comparison to RTL and easy design layout in comparison to ECL.

·        DTL has advantage of more fanout over RTL but propagation delay is relatively large.

·      In ECL each gate continuously draws current so it requires more power in comparison to other members of logic families.
