Abstract: Power consumption has emerged as a primary design constraint for today VLSI integrated circuits (ICs). AS per reducing Technology, mostly Nanometer technology regime, leakage power has become a major component of total power. Full adder is the basic functional unit of an ALU. The power consumption of a processor is lowered by lowering the power consumption of an ALU. In this paper we introduced low power consume one-bit full adders, including the most motivating of those are analyzed and compared for speed, leakage power, and leakage current. The simulation has been carried out on a Cadence environment virtuoso tool using a 0.45-m technology
