Basic building blocks of most of the arithmetic and logic circuits are formed by XOR logic gate. This paper proposes a new 3T - XOR gate with significant area and power savings. In most of the digital systems adder lies in the critical path that increases the overall computational delay of the system. A new eight transistors one bit full adder based on 3T - XOR gate is presented. Simulations results utilizin g standard 90nm CMOS technology illustrate a significant improvement in terms of number of transistors, chip area and propagation delay.
