Abstract

The performance of CMOS technology-based circuits has been affected because of channel length scaling, which had an impact on increased leakage current and more power dissipation in the overall circuit. QCA (Quantum-dot cellular automata) technology has the potential to overcome these challenges as it has an edge over higher operating frequency (THz), low power dissipation (nW), and less area. The proposed work shows an efficient implementation of an XOR gate (~60% in terms of area), 3-bit and 4-bit binary to gray, and 3-bit and 4-bit gray to binary code converters with a minimum number of QCA cells and latency than already prevailing designs. This paper shows various layout design implementations which have been designed using QCA designer tool version 2.0.3.
