A Low Power Adder Using Reversible Logic Gates

چکیده
Reversible logic has emerged as one of the most important approaches for the power optimization with its application in low power VLSI design. They are also the fundamental requirement for the emerging field of the Quantum computing having with applications in the domains like Nano-technology, Digital signal processing, Cryptography, Communications. Implementing the reversible logic has the advantages of reducing gate counts, garbage outputs as well as constant inputs. In contrast to conventional gates, reversible logic gates have the same number of inputs and outputs, each of their output function is equal to 1 for exactly half its input assignments and their fan-out is always equal to 1. It is interesting to compare both reversible and conventional gates. In this paper addition, subtraction, operations are realized using reversible logic gates like DKG and TSG gate and compared with conventional gates.
