Abstract
The present invention provides a latching mechanism for use in high-speed domino logic pipestages. The latching mechanism allows time borrowing across latch boundaries, provides sufficient hold time for the output to be sensed by the next stage, and provides a circuit configuration in which race conditions related to the latching mechanism have inherent positive margin. The latching mechanism of the present invention is applicable to fully self-resetting domino logic, globally resetting domino logic, or any combination thereof. The latching mechanism is a set dominant latch having its set input driven by the output of the last domino logic gate in a pipestage, and having its reset input driven by the output of the last domino logic gate in a pipestage ANDed with a delayed version of the pulsed clock that triggers the domino chain of the pipestage.
