Design Of Low Power 4-Bit BCD Adder Using Reversible Gates
Reversible logic is emerging as an important research area having its application in diverse fields such as low
power CMOS design, digital signal processing, cryptography, quantum computing and optical information processing. The
proposed BCD adder is efficient in terms of power dissipation. Various technologies are going to be used and respective
power dissipation will be compared. Logic Gates such as AND, OR, NAND (Except NOT) gates are not reversible that is
inputs cannot be recovered from the output. On the other hand, in Reversible Logic Gates inputs can be recovered
completely from the output that is there is one to one mapping between inputs and outputs. Reversible logic gates use less
power compared to classical gates and under ideal condition.
