摘要：Abstract Scaling down trend of CMOS transistor is approaching its lowest point, the rational substitute for the CMOS technology to attain advance improvements in terms of size, low power, and device density usage is an imperative essential. Due to the several physical limitations and circuit bounds of CMOS technology, it is the requirement of a new possible consistent model, that has small area, high device density and low power consumption. Quantum-dot Cellular Automata (QCA) is a novel approach in this direction. This paper presents a new design of 2:4 Decoder, 2:1 Multiplexer, D-Flipflop based on QCA. In addition, a nano communication circuit has been proposed which is proficient as compared to previous designs. Hamming distance approach has been used to perform the power calculations of the proposed circuits. To authenticate the functionality of the proposed designs computational simulation results has been performed using the QCAdesigner tool.
