The necessities to obtain better speed, this paper list to a change in parameter of full adder circuit that has been proposed by using 3T XOR gate combining CMOS with pass transistor logic. The design that has been given shows a significant improvement in propagation delay constrain. The proposed adder gives better propagation delay in comparison with the previously existing reference design. The 50nm technology has been used to investigate the performance of 8T full adder circuit and the complete design is simulated with the help of LTSPICE.
