I am working on a high-gain current-to-voltage amplifier. I need to
convert a very low pulsed current signal (100 microsec, <nanoamp)
into a voltage signal (>10 mV) that I can read from the scope. I
tried the amplifier using a low-gain (0.2 V/microamp) setting, and it
works ok. When I tried it with a higher gain (2 V/microamp),
oscillations (~10 microsec, regular amplitude) showed up on the scope
display. I'd like to fix that, but don't know how. I need some help,
if you know how to fix it and what is the cause of that, please let
me know. Thanks!
