Abstract
An N-domino latch includes a domino stage, a write stage, an inverter, a high keeper path, a low keeper path, and an output stage. The domino stage is coupled to an approximately symmetric clock signal. The domino stage evaluates a logic function according to the states of at least one data signal and the approximately symmetric clock signal, where the domino stage pre-charges a pre-charged node high when the approximately symmetric clock signal is low, and discharges the pre-charged node to a low state if the logic function evaluates when the approximately symmetric clock signal is high, and keeps the pre-charged node high if the logic function fails to evaluate when the approximately symmetric clock signal is high, where a latching state of the at least one data signal is provided to the domino stage when the approximately symmetric clock signal is high.
