Design of 3:2 Compressor Using Quantum Dot Cellular Automata

Abstract

Quantum-dot Cellular Automata (QCA) design is a promising technology for the nano-scale implementation of digital systems. It is a framework with low power utilization and a potentially high compactness. QCA promotes nanotechnology architecture for new devices. This system works on the basis of electron interactions within quantum dots that contribute to the emergence of quantum properties and reduces the problem of size for generation of future circuits. In this article 3:2 compressor is designed dependent on QCA with the less area, delay and intricacies. A 2-input XOR gate is used and a 2:1 multiplexer are used to propose the encoder. Thereafter it is extended to construct 3:2 compressor. The circuit proposed is constructed using the QCA Designer tool. Practical results are consistent with the principle that explains the suitability of the QCA circuitry.
