Dear friends,
In the attached image of the non-ideal op-amp, the quantities CMRR, PSRR, and Vos are modelled as voltage sources at the nin-inverting terminal. These sources together will offset the output with some value.
If I am interesting on finding the input offset voltage, how can I know that this output shift is not a result of the other two components CMRR and PSRR ?
Thank you
