[PDF] Design of Low Power and High Speed 4-Bit Ripple Carry ripple leather office chair ABSTRACT. Adders are one of the widely used digital components in digital integrated circuit design. The Carry Select Adder (CSA) provides a good compromise between cost and performance in carry propagation adder design. However, conventional CSA is still area-consuming due to the dual ripple carry adder (RCA).assumed all adder cells were implemented with static (restoring) logic. Therefore, the ripple-carry propagation delay was linearly proportional to the size of a block. This is in contrast to a more popular adder implementation in VLSI: the Manchester adder using precharge logic [6], [7], [8] in which the ripple-carry propagation  A Review on Performances of Reversible Ripple-Carry Adders
