Reversible logic has attained importance in the recent developments of high speed and low power digital systems. This factor calls for a performance analysis of different reversible binary to gray code converters. To know the different combinations of reversible gates used in the design for the construction of reversible binary to gray code converters, several binary to gray code converters are analyzed in this paper

Nowadays, reversible logic design is gaining more attention due to its low power loss. Earlier, Landauer (1961) showed that every bit of information loss will generate KTln2 Joules of heat energy, where K is Boltzmann’s constant and T is the operating Temperature. Later Bennett (1973) proved that the energy loss in a circuit can be eliminated by using reversible gates for the designing of circuits.

In digital systems, information is represented by 0 and 1 which is known as code. There are different codes available, a few of them are Binary, Excess-3, BCD, Gray, Octal and ASCII code. From the available number systems, binary number system is the most suitable and efficient format to represent data. To perform a few operations in Digital Signal Processor (DSP), microprocessors and microcontroller, code conversion from one format to another is necessary; this tends to the need for code converters in digital systems.
