The multiplexer is an integral design component of the conventional CMOS technology and modern QCA nanotechnology. It is also an elementary building block of nanocommunication networks and nanocomputing circuits. This article proposes a simple single-layer 2:1 QCA multiplexer without using any wire-crossing and majority voter. The proposed design outperforms prior reported works by ~ 17, ~ 20, and ~ 17%, in terms of cell count, total area measurement, and cell area need, respectively. In addition, an exhaustive energy dissipation analysis of the suggested multiplexer was performed using the tools QCAPro and QDE for a better performance evaluation. In particular, the suggested module is ~ 9% more energy efficient (according to QDE) and ~ 37% better energy-delay cost effective than the best previously reported design. According to QCAPro (γ = 0.5EK), the proposed design is ~ 31% more energy efficient than the earliest best-reported design. [ABSTRACT FROM AUTHOR]
