ABSTRACT:
A cycle latch includes a control circuit which increases the pull-up rate of a storage node by conditionally discharging the feedback node in a cross-coupled inverter keeper structure. The cycle latch includes an NMOS transistor switch for transferring an input value to the storage node, and two more NMOS transistors connected in series for performing the function of the control circuit. By connecting the storage node to a pre-discharged feedback node and then driving the latch with a low-swing clock, improved performance in terms of delay times, energy consumption, and robustness is achieved.
