【Abstract】 A charge self-compensation techniques,based on the dynamic node of the P-type charging dynamic node of N-type,is proposed in this paper.Utilizing this technique,the dual-threshold voltage techniques and the multiple supply voltages techniques a low power and high performance Zipper CMOS domino full-adder is designed.And a novel method of the power distribution is introduced.With this method,the optimal path of the proposed Zipper CMOS full-adder with the charge self-compensation techniques is found accurately to minimize the power.Simulation results prove that active power of proposed Zipper CMOS full-adder can be reduced by up to 37%,5% and 7%,and static power can be reduced by up to 41%,20% and 43% as compared to the standard,the dual threshold voltage,and the multiple supply Zipper CMOS domino full-adder under similar delay time,respectively.At last,the inputs and clock signals combination sleep state dependent on leakage current characteristics is analyzed and the optimal sleep state is obtained.更多还原
