Design and simulation of a QCA 2 to 1 multiplexer

Abstract

In this paper a novel design of a quantum-dot cellular automata (QCA) 2 to 1 multiplexer is presented. The objective is the development of a modular design methodology which can be used to design 2n to 1 multiplexers using building blocks. For the QCA implementation a careful consideration is taken into account concerning the design in order to increase the device stability. The proposed multiplexer is designed and simulated using the QCADesigner tool.
