I have the following inverting operational amplifier with these values:

- Rs = 1k ohms
- R = 10k ohms
- C = 10 mF
- Aol = 74dB
- Zin = inf
- Zout = 5 ohms

Got no issues with the first two, I found an expression for the transfer function dividing the impedance on the feedback network by the input impedance, this is what I got (sorry but it gives me an error if I try to use the math editor for some reason):

- Vo(s)/Vs(s) = - Zf/Zi = -(jwRC + 1)/(jw*Rs* C) = - (100jw + 1)/jw

Thank you very much for your help and sorry for the confusion!
