Reversible logic plays an important role in nanotechnology-based systems; therefore, it has become an interesting topic for many researchers in this field. Although many researchers are investigating techniques to synthesize reversible combinational logic, few are working in the field of reversible sequential logic. The traditional method to design a sequential circuit is a replacement technique. In this technique, in order to design a reversible sequential circuit, all parts of an irreversible…
