PhD Help in VLSI – Developing a PhD project in Low Power VLSI

Beginning in the 1970s, Very Large Scale Integration (VLSI), was used when communication technologies were being developed. VLSI is a process of creating an integrated circuit to help deal with the complex semiconductors and generate a microchip performing advanced functions of a primary transistor. With the small transistors, the developers saw the difficulties and complexities, thus bringing up the possibility of constructing advanced circuits. Howsoever, low power VLSI came to rescue for the complex circuits consuming large supply of power. 

With overall supply voltage lowered, the power loss of the circuits can be reduced to a large extent. Another reason to scale down the power is the voltage restriction. At a low power supply, a low voltage is preferable to maintain the balance in performance without compromising the frequency or the speed. Low power VLSI has emerged as an important research area because of the research scope it offers to the researchers. Researchers have a wide array of limitations and advancements to work on and improve the efficiency. 

However, how to develop a PhD project in low power VLSI? For finalising a research topic in low power VLSI, formulate an objective to consider. A researcher can choose the objectives like leakage power reduction, reducing dynamic power dissipation, glitch reduction, path delay optimisation. While power dissipation can be in divided into three categories : 

  • Dynamic power consumption
  • Short circuit current
  • Leakage current

A researcher has to study the literature on the basis of the objective formulated by him. Going through the literature of the formulated objective will help the researcher build research problem and know how to fill the existing gap of the literature. The scholar should analyse various recent researches to develop a framework of what has been performed recently in the field of low power VLSI. Once the objective and research problem is formulated, it gives a clear mindset to the PhD scholar to define a scope of the research and continue with it. The extent of the gap will help the researcher to overcome the issue.

Draw upon an algorithm to reduce the existing problem in current researches and to enhance the result. The conventional algorithms to minimise the issues are the genetic algorithm, local minimisation algorithm. An algorithm or technique is used to reduce the complexity, and maintain regularity in the functioning of the process. The low power design technique provides partitioning and power down system with logical style circuit and energy recovery, and threshold reduction technology.  The researcher should incorporate different objectives together and identify techniques for finalising the research scope. Once the proposed scheme of research is implemented, then compare the same with related recent researches and validate the proposed approach. There are various evaluation parameters to evaluate the studies and compare them; however, the comparison will lead the scholar to a better thesis. The research should be concluded by stating the effectiveness of proposed theme. 

The proposed theme and the research will undoubtedly be effective for the academic strata of the field to observe the results and findings of the research and use it to carry forward their research.
