That is correct. I had a typo, now corrected. Thank you for seeing it.

Why wouldn’t the single pole Transfer function be R/(RC*jw+1) ?
For the simple voltage source and RC circuit the transfer function would be 1/(RC*jw+1)

Thanks a lot for posting this detailed example of Op-Amp. It was really helpful.
Just one question though, how can we setup the supply voltage Vsy = +/-15V in this circuit i.e. V+ & V- in ADA4004-1 model ? I tried to connect the photodiodes b/w V+ & output and V- and output as suggested by you previously in comments. But this reduces the V(out) OR output Gain by a magnitude of order of 1000.

If I understood correctly, that’s how we setup the V+/V- OR in general terms the Vcc+/Vcc- power supply nodes?

Thanks a lot.

Thank you Adrian. And also, appreciate the work you’ve done.

Place a positive power supply and a negative power supply at the op amp output. Connect a diode with the anode at the output and cathode at the positive supply. Connect another diode with the cathode at the output and the anode at the negative supply. The positive power supply value has to be the maximum op amp’s output trip plus 0.6V (a diode drop) and the negative supply value has to be the minimum op amp’s output trip minus a diode drop.

I do not have any signal with a duty-cycle in this article. If you want me to help you need to tell me what article/schematic/figure you are taking about. Or, if this is a general question, let me know in what context.

Thank you, Whitney.
