Colleagues,
I'm designing a transimpedance amplifier for sensing a 3nA DC current. I have found this schematic (picture below) and I like it. However, I'd like to add some low-pass filtering. Where should I add the capacitor(s)? In parallel with R2? Can I get a 2-pole filter or only 1-pole?
Thanks,
Nick
