Design and validation of ALU using m-GDI at 16nm Technology

Abstract

            It is suggested to build and develop an 8-bit arithmetic logic unit (ALU) utilising the Gate Diffusion Input (GDI) method. When developing the ALU, the GDI approach leads in reduced power consumption and a decrease in the number of transistors. It reduced chip-area and low power consumption. Here 4T XOR is used in the full adder. In this design 1-to-8 de multiplexer circuit is used . A 8-bit ALU  perform 8 different operations .
