Abstract :
Full adders is the basic building block of ALU and ALU is a basic functioning unit of the microprocessors and DSP. In the world of technology it has become essential to develop various new design methodologies to reduce the power and area consumption. In this paper transmission gates have been used to develop the proposed full adder using 6 transistors XOR gates. The carry logic has been efficiently implemented using 2×1 MUX to reduce transistor count. The reduction in Transistor count results in improved area and power consumption. The proposed full adder has been designed using 27 and 18 transistors using 90 nm technologies. The developed adder with 18 transistors has shown an improvement of 6.624% in power and 31.765% in area so as to implement adder efficiently in digital signal processors.
