Colleagues,
I need to design a circuit that would detect a 3nA current through a slice of tissue. A crude block diagram is attached. It’s ok, if the detection takes a few seconds. The input voltage is between +2V and +3V.
Please give me some ideas, hints or reference designs.
Thanks,
Nick
P.S. This is an academic project, but not homework.
