PSRR in Bandgap
i think it s better to have a good PSRR esp for a bandgap since it will be used as a source. The BG that i designed has 70dB rejection till 200KHz though i dint do anything in specific to improve it.
The SNR that I had received while calculating in Matlab for a specific NTF is around 80 dB. I realised the same using ideal op amps and the SNR was the same. But the SNR after using nonideal op amps went down to 40 dB. What can be the reasons for the degradation?

miller compensation in op-amp.
Miller compensation is done is introduce a zero at the pole position and cancel the effect of the pole. but in a telescopic cascode , between which two nodes can you introduce a zero to cancel it out? introducing Cc between negative terminal and output seems a bad...
