Domino keeper has to be upsized to keep the noise margin in high fan-in dynamic gates, which increases the power consumption and slows down the evaluation. We propose a four-phase non-full swing keeper design to solve this dilemma. Non-full swing switching at the keeper gate together with alleviated contention help to reduce power consumption and delay. Simulation of 16-input OR gate using 0.13um CMOS SPICE parameters shows that proposed keeper design can reduce power consumption and delay by 26% and 24%, respectively.
