摘要:
In some embodiments, the invention includes a domino circuit having a precharge circuit including a source follower nFET device coupled to a domino stage conductor. An evaluation path circuit is also coupled to the domino stage conductor. A hysteretic output stage receives a signal from the domino stage conductor and provide therefrom an evaluated output signal. In other embodiments, the invention includes a domino circuit having a predischarge circuit coupled to a domino stage conductor. An evaluation path circuit includes source follower nFET devices coupled to the domino stage conductor. A hysteretic output stage receives a signal from the domino stage conductor and provides therefrom an evaluated output signal. In still other embodiments, the invention includes a domino circuit having a precharge circuit including coupled to a domino stage conductor. An evaluation path circuit is coupled to the domino stage conductor. An output stage includes an inverter to receive a signal from the domino stage conductor and to provide an evaluated output signal on an output conductor, the output stage including a duplicate evaluation path circuit coupled to an output conductor.
