Abstract
An N-domino register has a domino stage, a write stage, an inverter, a high keeper path, a low keeper path, and an output stage. The domino stage evaluates a logic function based on at least one input data signal and a pulsed clock signal. The pulsed clock signal lags a symmetric clock signal. The domino stage pre-charges a pre-charged node high when the symmetric clock signal is low and opens an evaluation window when the pulsed clock signal goes high, and pulls the pre-charged node low if it evaluates, and keeps the pre-charged node high if it fails to evaluate. The output stage provides an output signal based on states of the pre-charged node and a second preliminary output node.
