Quantum-dot cellular automata-based superior design of conservative reversible parity logic circuits

الملخص EN

Quantum-dot Cellular Automata (QCA) is an innovative technology in the nano-scale for changing the CMOS revolution with an alternative one.

It provides some benefits in reversible logic, like competitive power consumption and feature size.

Therefore, much attention is paid to producing different reversible circuits using that technique.

This paper presents a superior model for a reversible Feynman gate-based odd parity generator and checker.

The proposed model can be utilized for loss bit detection /checking in telecommunication systems.

The circuit verification is carried out using the QCADesigner tool.

The proposed Feynman gate provides an improvement of 50% and 48% in terms of latency and cost, respectively.

The parity generator, parity checker and nano-communication circuit have complexity reduction by 25%, 37% and 24%, respectively, in terms of requiring cells.
