Implementation of sequential circuit using feynman and fredkin reversible logic gates

Abstract At present, one of the most vital issue is reversible logic and this reversible logic has various applications in different areas such as low power CMOS, quantum computing, nanotechnology, cryptography, Digital Signal Processing(DSP), quantum dot cellular automata. A unique one-to-one mapping technique is used in reversible logic gates. To create a helpful capacity of gates, the reversible gates require some supported auxiliary data sources known as ancilla inputs. Likewise to keep up the reversibility of the circuits some extra unutilized yields are requiring that are referenced to as the trash yields. The quantity of garbage outputs, the quantity of ancilla sources of info and quantum cost assumes a noteworthy job in the reversible circuit’s assessment. Subsequently these parameters are most enormous for structuring reversible circuit’s effectively. In this paper implementing the sequential circuit using Feynman and Fredkin reversible logic gates. The proposed sequential circuit is simulated using Tanner Tool. The result shows that overhead delay and total delay are reduced by 33.69% and 20.42% respectively.
