Design of Power Reversible Comparators with Different Technologies

In this article the comparison of GDI and TG based Reversible Comparator circuits using 90 nm and 180 nm Technology has been considered. Because of the applications of these circuits in different fields, these are also considered as fundamental requirement in quantum computing. Here transistor implementation of the reversible gates is done by using a combination CMOS-GDI circuit, TG Circuits, which provides the optimal solution for combinational logic, saving 1/3 the power, half the area and 10% in delay relative to a CMOS implementation. GDI circuits provide some measure of enhanced hazard tolerance and are more suitable for low voltage operation. Here transistor implementation of reversible gates is done by using Tanner tools and H-spice tools.
