摘要

A high-speed, state-preserving, race-reducing, wide-pulsed clock domino design style. For one aspect, a pipestage in accordance with the wide-pulsed clock design style includes one or more domino logic stages and a wide-pulsed clock generator to provide a wide-pulsed clock signal to control evaluation of the one or more domino logic stages in response to receiving a two-phase input clock signal. The wide-pulsed clock signal has a pulse width that tracks a phase width of the input clock signal over a first frequency range where the first frequency range extends at least from a predetermined fraction of a nominal clock frequency to an upper frequency limit for the circuit. For one aspect, ratio logic is coupled to at least one of the domino stages. The wide-pulsed clock signal provides sufficient time for the one or more domino logic stages to evaluate while preventing infinite or very long contention in one or more ratio logic stages when the input clock signal is stopped or slowed down significantly.
