what could be done to check the circuit against temperature and supply voltage variation in spectre. i have done worst case simulation . is it sufficient?
 

for temp, run sweep parameters
for supply voltage, run .ac to get pssr.

check the result.
 

Hi Sunking,

Can you explain more specific on "for temp, run sweep parameters
for supply voltage, run .ac to get pssr".

You mean run parametric analysis for temperature? I don't get you for PSRR analysis. Pls explain the method.

Regards,
suria
 

For temperature sweep,choose "temp sweep" at DC analysis in spectre.
For supply variation,series a ac source on the input supply,then choose "ac" analysis in spetre.Plot Vo/Vin,it is PSRR.
