» ABSTRACT In this project, two high performance adder cells are proposed. We simulated these two full adder cells using HSPICE in 0.18 µm, CMOS technology and at 25 degree of temperature with supply voltage range from 0.5v to 3.3v with 0.1v steps. Results show that the proposed adders operate successfully when connected to a 0.5 V power supply. The two adders differ in the technology applied ...Continue Reading »
