Amplifying micro/nano Amp signals

Hello guys,

I need to amplify a micro/nano Amp current signal. Then I need to convert this amplified signal to a voltage so a 10 bit analogue to digital converter can read it. I assume I would use some sort of current amplifier followed by measuring the output voltage across a resistor. Is there anything I am missing that the experienced/clever heads in this forum can point out! Thanks in advance,

Ping.

p.s if anyone knows of any good current amplifiers please suggest, thanks.

Before anyone can suggest a solution they would need to know more about the source of this μA/nA signal?

What is the device?

Thanks for that guys. Yes I have stumbled on a transimpedance amplifier since, so that is what I should stick too!

crutschow, the frequency of the signal is basically just on/off from time to time, i.e not high frequency.
