Hi,
Don't have any material just some comments:
1) Simply put power supply are inputs. PSRR gives the ratio of the gain from the power supply to the output over the gain from the standard inputs to the output.
2) While PSRR is typically specified as XdB at YHz, you also need to consider the dc levels of the inputs, the output, and the power supply. All of the dc levels and can effect the ac results.
3) Depending on the circuit, i.e., differential circuits, there may be canceling due to symmetry. In that case, you need to analyze the effect of device mismatch on PSRR.
4) Measure the open loop gain, and then move ac input to the power supply terminal and then take the ratio., the ADE calculator is good for this type of calculation.
