Design and implementation of an efficient single layer five input majority voter gate in quantum-dot cellular automata

The fundamental logical element of a quantum-dot cellular automata (QCA) circuit is majority voter gate (MV). The efficiency of a QCA circuit is depends on the efficiency of the MV. This paper presents an efficient single layer five-input majority voter gate (MV(5)). The structure of proposed MV(5) is very simple and easy to implement in any logical circuit. This proposed MV(5) reduce number of cells and use conventional QCA cells. However, using MV(5) a multilayer 1-bit full-adder (FA) is designed. The functional accuracy of the proposed MV(5) and FA are confirmed by QCADesigner a well-known QCA layout design and verification tools. Furthermore, the power dissipation of proposed circuits are estimated, which shows that those circuits dissipate extremely small amount of energy and suitable for reversible computing. The simulation outcomes demonstrate the superiority of the proposed circuit.
