Attached is my simulation for a switched current source. It would be switched at 1Khz.
Simulation produced sufficient results although I had to add a 100nF cap across the switching mosfet in order to attenuate massive spikes due to fast switching time of the pulse generator.
It was set to 100ns. I would be driving the mosfet gate by a microcontroller. Do you think this solution is practical enough?
This would be the first stage of a lock-in detection circuit for a milliOhmeter.
thanks
