摘要:
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.
