Design methodology to optimize the speed and power of the ultra scaled CNTFET circuits

Abstract

Presently the battery life and high spectral efficiency are found to be a perennial problem in smartphones With the advancement in the technologies towards 5G it has become mandatory to meet these challenges before problems are aggravated Besides CNTFET technology is found to be a promising field of research that is recommended in this work to solve the problem of battery life A Carbon Nano Tube Field Effect Transistor CNTFET has become one of the strong nominees to substitute silicon by its contribution of low power performance In the first phase of the work an experimental investigation is conducted to find the most influencing parameter by multivariate regression analysis using Hybrid PSO technique for obtaining the maximum performance in CNTFET The main parameters that were taken into consideration were thickness of nanotube length of the tube number of nanotubes pitch diameter of the nanotube temperature number of bias points in gate number of bias points in drain and threshold voltage Among these parameters the most impacting parameter was examined CNTFETs have better threshold high current density and high electron mobility when compared to traditional CMOSFET The main advantage with CNTFET is that it minimizes the short channel effects of existing Nano scaled MOSFET with cylindrical channel structure Recent studies on CNTFET show that thermal and electronic characteristics of CNTFET change with respect to change in length diameter and gate properties newline
