Design of Asynchronous Sequential Circuits using Reversible Logic Gates

In recent literature, Reversible logic has become one of the promising arena in low power dissipating circuit design in the past few years and has found its applications in low power CMOS circuits , optical information processing and nanotechnology. The reversible circuits form the basic building block of quantum computers as all quantum operations are reversible. This paper presents asynchronous sequential circuits and circuits without hazard effect using reversible logic gates. I illustrate that we can produce AND, OR, NAND, NOR, EXOR and EXNOR outputs in one design using reversible logic gates. Also, I will evaluate the proposed circuits. The results show that reversible logic can be used to design these circuits. In this paper, the number of gates and garbage outputs is considered.
