Abstract
A shut-off circuit included in a dynamic flip-flop isolates output terminals of the dynamic flip-flop from circuitry within the flip-flop that could introduce noise on either output terminal during a portion of the evaluation phase. Since the output terminals are isolated from the input terminals during this portion of the evaluation phase, spurious input signals have no affect on the output signal levels. Similarly, charge within the dynamic flip-flop that is not completely dissipated in the transition from a precharge phase to the evaluation phase has no affect on the output signal levels during this portion of the evaluation phase.
