Abstract
An edge-triggered, self-resetting pulse generator where a pulse is initiated by a voltage transition and is reset using feedback from the output. A voltage transition is presented at one input of a two-input NOR gate and at the input of a circuit with three inverters in series. The output from the circuit with three inverters in series connects to the second input of the two-input NOR gate. This combination creates a voltage pulse that drives a transfer FET. The transfer FET creates a voltage on a latch. The latch stores the voltage presented on the input and then drives a delay-chain with an odd number of inverters. The output of the delay-chain drives a second transfer FET that resets the latch.
