Layered T Parity Generators using Quantum-dot Cellular Automata

The Parity Generators and checkers are crucial block in Central Processing Unit especially in the process of Error Detection and correction during data transmission. In this work, the three-bit Quantum Cellular Automata (QCA) even parity generator have been proposed using Layered T AND and OR Gate. The proposed comparator layout needs 9.02% less effective area compared to the best reported design so far. Moreover, the other QCA design metrics such as Effective Area, O-Cost, Costa, Irreversible Power Dissipation, and Complexity are analyzed for the proposed Parity Generator circuit. The functionality of the proposed circuit is verified by computer aided design tool QCADesigner.
