Abstract
A dynamic flip-flop includes first and second input stages forming a differential input stage adapted to receive differential data. The flip-flop is reset in response to a reset signal. To ensure proper operation, a transistor disposed between the first and second input stages is always maintained active to provide a conduction path between the ground terminal and the nodes that may be charged from the supply voltage. To improve the setup and hold time of the flip-flop, the clock signal is applied to a first transistor disposed in the first input stage and a second transistor disposed in the second input stage.
