Tile-based N-variable Symmetric Logic Function Syntheses in Quantum-dot Cellular Automata

Abstract

Tile Nanostructures in Quantum-dot Cellular Automata (QCA) are proved to be a robust and reliable structure to fabricate the logic device. In this scientific attempt, we have focused on N-variable symmetric Logic function synthesis in Quantum-dot Cellular Automata with tile nanostructure. Coupled Majority-minority voter (CMmV) voter is applied to implement 2 –variable and 3 –variable logic syntheses in Quantum-dot Cellular Automata. The N-variable symmetric logic function is applicable to implement any logic circuit. Two and three variables Quantum-dot Cellular Automata symmetric logic functions are synthesized in this article. Hence any digital logic circuit can be implemented with proposed Coupled Majority-minority voter (CMmV).
