This paper presents a new 8-bit adder circuit, called discrepant low PDP 8-bit adder (DLPA) based on three new full adder cells, which have been designed based on requirements of different positions in each 8-bit adder circuit. In order to design the full adder cells, a new and general method has been proposed aiming to achieve full-swing output and low number of transistors. The proposed adder along with several state-of-the-art adders from the literature have been extensively analyzed and compared together. The results revealed that the power-delay product of DLPA is almost more than 20 % less than that of other compared circuits. [ABSTRACT FROM AUTHOR]
