The principle part of ALU (Arithmetic rationale unit) is the Full Adder. This paper tells the best way to perform quick arithmetic activities created utilizing GDI. The fundamental point of this paper is to plan the full adder of two semiconductor utilizing Gate diffusion input (GDI) strategy. The plan of full adder is appropriate for the two semiconductor EX-OR gate. The primary intension of novel technique is fully founded on Full adder plan of 2TEX OR gate which is utilized to decrease power and improve the speed with an advanced territory of number of semiconductor check which is less similar with CMOS innovation. The best strategy for GDI is to plan advanced rationale circuits and which will in general improve the conditions.GDI system is functional to Full adder plan. The Cadence apparatus is to figure power, postponement and region for two semiconductor EX-OR gate .The total work is done in 45 nm innovation. The investigation of the outcomes show that the planned strategy is superior to traditional CMOS innovation.
