2 n :1 Reversible Multiplexer and its Transistor Implementation

The advantages of reversible logic systems and circuits have drawn a significant interest in recent years as a promising computing paradigm having applications in low power CMOS, quantum computing, nano technology, digital signal processing, computer graphics, cryptography and optical computing. In this paper, new reversible PV gate is proposed and the design of 2:1, 4:1 and 8:1 reversible multiplexer using the proposed reversible gate is discussed. Transistor implementation of proposed gate is done using virtuoso tool of cadence. Based on the result of the analysis, some of the trade-offs are made in the design to improve the efficiency.
