Low Power 4-Bit Arithmetic Logic Unit using Full-swing GDI Technique

Power dissipation and area of the circuit are the main issues in the electronics industry, this paper provides a design of 4-Bit Arithmetic Logic Unit (ALU) using Full-Swing GDI Technique, which considered an effective method for low power digital design while reducing the area of the circuit compared to other logic styles. The proposed ALU design consists of 2×1 Multiplexer, 4×1 Multiplexer and low power Full Adder cell to realize the arithmetic and logic operations. The simulation carried out using Cadence Virtuoso using 65nm TSMC process. The results show that the proposed design consume less power using less number of transistors, while achieving full swing operation compared to previous work.
