An Efficient CNTFET Based 7-Input Minority Gate

Abstract

Complementary metal oxide semiconductor technology (CMOS) has been faced critical challenges in nanoscale regime. CNTFET (Carbon Nanotube Field effect transistor) technology is a promising alternative for CMOS technology. In this paper, we proposed a novel 7-input minority gate in CNTFET technology that has only 9 CNTFETs. Minority function is utilized in the voting systems for decision making and also it is used in data mining. This proposed 7-input minority gate is utilized less fewer transistors than the conventional CMOS method which utilizes many transistors for implementing sum of products. By means of this proposed 7-input minority gate, a 4-input NAND gate can be implemented, which gets better the conventional design in terms of delay and energy efficiency and has much more deriving power at its output.

Comparative Analysis of CNTFET and CMOS Logic based Arithmetic Logic Unit

“…Lithography limitations, large parametric variations, high power density are some of these critical challenges. To overcome these difficulties and challenges in sub-nanometer scale new technologies have emerged [2]. A carbon nano tube field-effect transistor (CNTFET) refers to a field-effect transistor that utilizes a single carbon nano tube or an array of carbon nanotubes as the channel material instead of bulk silicon in the traditional MOSFET structure.…”

“…The static DCVS-based standard ternary gates (Inverter/ Buffer, AND/NAND, OR/NOR), which are fundamental components of every arithmetic or logic units, are proposed with the use of CNTFET technology [12]. Minority function is utilized in the voting systems for decision making and also it is used in data mining [13]. The threshold voltage of the intrinsic CNT channel can be approximated to be of first order as the half band gap is an inverse function of the diameter [14][15] Fig.…”
