Can someone please explain how PSRR of folded cascode opamp is calculated with detail analysis . More intuitively if possible .
Thank you

Connect differential inputs with DC source, no ac signal. Add ac=1 at VDD source. Now you are injecting ac noise at VDD. Run AC analysis from 1 to say 1GHz. Plot opamp Vout. This will tell you how is the Vdd noise attenuation at the Vout. More the negative value, the better is PSRR. Hope this helps.
