PERFORMANCE ANALYSIS OF CMOS COMPARATOR AND CNTFET COMPARATOR DESIGN

Vipin V. Kashti, Reena Monica

Abstract: This paper presents an efficient, low power, fast-response Carbon NanoTube Field Effect Transistor (CNTFET) based comparator and shows the simulation results for the basic performance parameters for it. Due to the properties of Carbon Nanotube (CNT) the CNTFET devices show faster performance as compared to that of complementary metal oxide semiconductors (CMOS) devices. And hence CNTFET based comparator has to show much more improved performance compared to comparator design using CMOS. The performances such as delay, power and the transient results of the CNTFET comparator simulation are much more efficient. Both comparators are simulated in CADENCE.

Keywords: Carbon Nano-Tube Field Effect Transistor (CNTFET), MOSFET, CADENCE, Comparator, Delay and Power.
