Hello, I am working on a project where I am receiving a very small current signal (~100 pA - 10 nA) and I would like to convert this into a voltage signal and amplify it up to something that is more reasonable.
Firstly, to convert this into a voltage signal, is the best method just to pass the current through a resistor and take the voltage drop as the new input voltage signal?
Secondly, I will be dealing with an electrochemical signal current that is far from sinusoidal, as you can imagine. I am just curious if my previous knowledge of small-signal analysis and amplifier design will be sufficient to process this signal.
Any advice would be greatly appreciated!
