Abstract
The provision of a clock chopper, pulse shaper, single-shot circuit with NOR gates a delay path and a set-reset latch. In response to a high input (for example) to a first NOR gate, the circuit output goes high and remains high until the output of the one NOR gate propagates through the delay one input of a second NOR gate whose other input is coupled to a set-reset latch. When the delayed output of the first NOR gate reaches the input of the second NOR gate, the circuit output falls, and the change in circuit output is fed back to reset the latch. The change in latch state changes the output state of the second NOR gate and resets the circuit for next input.
