摘要：

A new methodology to realize efficient multiplexers using quantum-dot cellular automata (QCA) is presented in this paper. The novel designs here demonstrated fully exploit the intrinsic logic capabilities of the basic building block in the QCA domain: the Majority Gate. An efficient logic formulation is derived for the 4:1 multiplexing function that can be recursively applied to the realization of multiplexers with any fan-in, by adding in the worst-case path only one level of Majority Gate for each input doubling. A 16:1 multiplexer designed by applying the proposed recursive approach requires less than 1600 cells and consumes only 12 clock phases to complete the operation.
