Hi ,

Can anyone guide how to simulate for PSRR of voltage regulator using cadence spectre.Thanks in advance.

SIRIUS,

Do you mean line and load regulation of the Voltage Regulator
or PSRR of the op-amp used in the Voltage Regulator? Are you
interested in small-signal effects, for example, 60dB of rejection,
or are you interested in large signal effects, 3mV/V of supply
variation?

Best Regards,

Sheldon

I mean line and load regulation of the Voltage Regulator & interested in small-signal effects & large signal effects.
