Hello,
I 've read in Allen's book that the procedure for simulating PSRR in an opam as a function of frequency is the following:
1. Connect the output of the opamp to its negative input (buffere connected opamp)
2.Add a small AC source in series with Vdd
3.Calculate PSRR by PSRR=Vdd/Vout
For the circuit shown in the picture, which is a single input amplifier, is the PSRR of the total system equal to the PSRR of the feed forward amplifier?
If not, how can i measure it ?
Thanks in advance
