ABSTRACT:
A pulse generator circuit. The pulse generator circuit includes a precharge circuit coupled to receive a clock signal alternating between a first logic level and a second logic level, a storage circuit having a storage node, wherein the precharge circuit is configured to precharge the storage node when the clock signal is at the first logic level, a logic circuit having an output, a first input node coupled to receive the clock signal, and a second input node coupled to the storage node and configured to produce a pulse at the second logic level responsive to the clock signal transitioning to the second logic level, and a discharge circuit configured to discharge the storage node at a predetermined delay time subsequent to the clock signal transitioning to the second logic level, wherein the output of the logic circuit transitions to the first logic level responsive to discharging the storage node.
