Carry-increment adders are commonly used due to its small size and fast speed. However, if the number of input bits is large, the speed would be much slow and the power consumption would increase because of its large fan-outs. This paper proposes the way to keep the number of fan-outs three regardless of the number of input bits. The 36 bit adder simulation result shows that the speed can increase up to 24% compared with the conventional design.
