Hello all,
I am trying to design a circuit to convert current to voltage.
The problem is that I have a 1kHz AC signal of 200 nA of amplitude that is carried on top of a DC current offset of 2mA . I would likemake the conversionl from current to voltage and then clear the the DC offset so I can get just the AC signal.
Do you think that a Transimpedance Amplifier circuit can help me doing that?
I am trying to understand the limitations (if any) of the TIA regarding the bandwidth of the signal I am trying to isolate (1KHz)
I am also worried about the fact I try to detect a small signal on top of a much larger DC offset.
Finally how what id the best way to deal with the noise of the system?
I can provide more info if needed.
Thanks in advance for any and all help!
