Analogue circuit
« on: December 03, 2017, 03:48:40 am »
after i run the simulation, based on my circuit.
why the output voltage decrease from the beginning and increase after a period of time?
shouldn't be the output should be in steady state?

Did you do a wire/node check prior to sim ? Pic makes it
look like MOSFET source may not be wired to ground
properly.
