HI,

I am new to LDO design. How to setup PSRR simulation in cadence for LDO?
What are the general methods to improve PSRR of LDO ?
 

Add a AC voltage source (1volts) at supply voltage and do AC simulation. Check output by dB.
Increase DC gain to increase DC PSRR. Increase bandwidth to increase high frequency PSRR.
