Abstract

Background and Objectives: This study presents the importance of reversible logic in designing of high performance and low power consumption digital circuits. In our research, the various forms of sequential reversible circuits such as D, T, SR and JK flip-flops are investigated based on carbon nanotube field-effect transistors.
Methods: By simultaneous using of the reversible logic gates and carbon nanotube transistors in implementation of various flip-flops and introducing suitable transistor circuits of conventional reversible gates, all reversible flip-flops are simulated in two voltages, 0.3 and 0.5 Volt. The Hspice_H-2013.03-SP2 software is used to simulate these circuits using the 32nm CNTFET technology (the standard Stanford spice model).
Results: The simulation results indicate a significant reduction in the average power consumption of D, T, SR and JK flip-flops, respectively about 99.98%, 82.79%, 60.46%, and 81.53%.
Conclusion: Our results show that the proposed structures have achieved a high performance in terms of average power consumption and PDP.
