Pulse Generator

by malabdalicircuit design
first one is not pulse but second one is pulse
rising edge + falling edge
pulse with mosfet
but the problem with this the input should to be high for period until the capacitor discharging and Q2 become in saturation mode
This is similar to the previous circuit but we add latching since Q2 at cutoff region Q3 in saturation mode
this is an useful example how to use generate pulse to reset a counter since you powering the circuit
