Majority logic gate synthesis approaches for post-CMOS logic circuits: A review

Abstract

Majority gates are fundamental logic gates that can be implemented in several potential post-CMOS technologies such as Quantum-dot Cellular Automata, Single Electron Transistor, and Tunneling Phase Logic. It is expected that these technologies provide more dense circuit integration levels than current CMOS technology. In this paper, a review of existing synthesis techniques targeted for majority logic gates are presented and compared.
