DESIGN OF LOW POWER NOVEL GATE

Abstract

Reversible logic gate design recovers the output from the input itself which is the novel gate for low power. This technology is widely used in VLSI design due to its low power. To achieve this, the number of input and outputs in the gate is equal. The function of the logic gates purely depends on the quantum cost function. Garbage output of the gates is ignored. Varieties of logic gates are available in the VLSI design. In this paper, different reversible logic gate functions are discussed. Also, it compares different adders with different gates.
