Abstract—Reversible logic is one of the most essential issues at present time due to its power reduction capability in circuit designing. It finds application in various fields including quantum computing, optical computing, nanotechnology, computer graphic, cryptography, digital signal processing and many more. Dissipation of a significant amount of energy is achieved in the conventional digital circuits because bits of information are erased during the logic operations. Thus, if logic gates are designed in such a way that the information bits are not destroyed, then it is possible to reduce the power consumption dramatically. The information bits are not lost in case of a reversible computation. This has led to the development of reversible gates. The reversible circuits do not lose information and can generate unique outputs from the specified inputs and vice versa. The main purposes of designing reversible logic are to decrease quantum cost, depth of the circuits and the number of garbage outputs. This paper represents the realization of different multiplexers by using COG reversible gate and a comparison of cost metrics of different multiplexers. Also the COG gate and multiplexer by this COG gate have been simulated by XILINX and implemented in the SPARTAN-FPGA Kit.
