Hi,everyone!
I have one question of simulation for psrr of a amplifier.
usually,psrr is below 0dB,is it possible that psrr curve can be above 0dB at high freq(why?),and why it is relative with the output cap. if the output cap is high,psrr is all below 0dB, and if output cap is lower(such as 100p or 1n), psrr curve can be above 0dB.
Thank you for reply in advance!
