Comparative Analysis of 20NM Based CNTFET for Different Logic Circuits

In this paper a comparative analysis of MOSFET and CNFET Based Binary Logic Circuits is shown. The binary logic circuits were implemented, viz. the inverter, two-input NAND and two-input NOR gates first using MOSFET, and then by CNFET, with logic in both the cases being CMOS. The comparison between the devices is made using average power, propagation delay and power delay product. The CNFET based circuits have performed better than the MOS based ones on all the parameters, with 98.77%, 82.53% and 96.68% optimization in the Power Delay Product (PDP) of an inverter, 2-input NAND and 2-input NOR circuits respectively. The tool for implementation is hspice on 20 nm technology.
