Design and Implementation of Optimal QCA Nanotechnology based Low-Power Combinational Circuits

Abstract

CMOS technology is nearly approaching its fundamental physical limit, a replacement technology for it is required. One technique that has the potential to surpass the well-known CMOS is Quantum-dot cellular automata (QCA). In terms of energy efficiency, integration density, and switching frequency, quantum-dot cellular automata (QCA) technology is regarded as a potential substitute for circuit implementation. Considered a viable option for developing QCA circuits is the multiplexer (MUX). distinct structures for 2: 1 MUX designs that are energy-efficient are suggested because These MUX structures can be utilized as the foundations of a new energy-efficient structure to replace QCA's majority-based structures. In this paper and designed different combinational circuits like adders and compressors are designed using QCA technology.
