Hi,

I am doing PSRR simulation of Bandgap Reference in Spectre. Please, let me know the simulation set-up procedure :

I have applied 1V AC signal in Vsupply and did AC simulation and plot Vout in dB scale.
Is it correct way to simulate PSRR of Band Gap reference. Please also review following results .

I have gone through past interaction but, It doesnt give complete idea. Please, briefly explain rather than one line answer.

Thank you.
