A 7-Input Minority gate design using Carbon Nano Tube Field Effect Transistor (CNTFET)

Abstract

Carbon Nano Tube Field Effect Transistors (CNTFET) Technology are being widely studied as the alternative to the conventional Complementary Metal Oxide Semiconductors (CMOS) Technology. .Due to the increased demand of high speed processors, compact circuits, smaller dimensions and lower power consumption of integrated circuits has made Engineers and designers a challenging issues of technology scaling of electronic devices. Hence it is now necessary to adopt and study new materials and technologies. In this project, we proposed a design of CNTFET–based digital circuit and compared it with the existing CMOS technology based logic gates . For CNTFET-based circuits, the compact SPICE model can be used for simulations, which is the standard model that has been designed for simulating one or more CNTs devices by Standford University. The performance of CNTs can be evaluated in terms of power, delay, and PDP at room temperature. In this project a novel 7-input minority gate is proposed in CNTFET technology with 9 CNTs . With this proposed implementation of 7-input minority gate, different logic gates such as a 4-input NOR and 4-input NAND gates can be design which gives better performance in terms of its delay and energy efficiency with more driving power outputs.
