Design and simulation of modular 2~n to 1 quantum-dot cellular automata (QCA) multiplexers

摘要

In this paper a novel design of a quantum-dot cellular automata (QCA) 2 to 1 multiplexer is presented. The QCA circuit is simulated and its operation is analyzed. A modular design and simulation methodology is developed, which can be used to design 2~n to 1 QCA multiplexers using the 2 to 1 QCA multiplexer as a building block. The design methodology is formulated in order to increase the circuit stability.
