Hi everyone,
I am working on a high voltage (0 to ~150 volts and low current < 1 ma) circuit that has a DC, square wave, triangle wave, and sawtooth wave source from an op-amp.
I tried to implement the switch (picture attached) but I keep on getting leakage current when my switch is 'off' or my base voltage is '0' volts. The leakage current is greater with a square wave input and almost non existent with a DC input. I am assuming it is due to the parasitic capacitance.
Is there another transistor scheme that I can use to prevent this leakage current from going through? Or even a digital input IC switch that I can use? I want to stay away from relays if possible.
Thanks a bunch!
