Reversible logic is one of the most important issues at present time and it has different areas for its application. The main purposes of designing reversible logic are to decrease quantum cost, depth of the circuits and the number of garbage outputs. A new reversible gate COG is proposed in this paper. This paper also represents an ease implementation of 4 –bit arithmetic circuit for 8 operation by using the reversible COG gate .
