Amplifying reverse saturation current

[-A-]

Forgive me for the noobish question, but here goes.

My objective is to feed the reverse saturation current in a circuit into a DAQ device for detection. However I want to amplify it from the micro to milli or ampere range before doing so, due to DAQ specifications.

I'm confused as to how exactly i can achieve this, and how the circuit setup should be. I've read on the working of operational amplifiers, but am still confused about as how to effectively implement them into the circuit.

This is my first project, and I've never used a DAQ card before, so forgive any ignorant mistakes I might be making, but how exactly can I do this?

Your help is much appreciated.

Thank you.

OK, if this is your first project, you need to study some basics before getting into specific questions. I would start here:
