Abstract

To construct a reversible sequential circuit, reversible sequential elements are required. This work presents novel designs of reversible sequential elements such as D latch, JK latch, and T latch. Based on these reversible latches, we also construct the designs of the corresponding flip-flops. Comparing with previous work, the implementation cost of our new designs, including the number of gates and the number of garbage outputs is considerably reduced.
