Title: PSRR vs PSR
Post by newic on Jun 9^th, 2011, 7:16am

Is PSRR (power supply rejection ratio) same as PSR (power supply rejection)??

PSRR= 20log [ delta_Voutput / delta_Vsupply ]

hello,
that def vary from person to person. However useful thing is ratio gain from supply to output/gain from input to output. This i guess so called PSRR. psr means gain from supply to output.

Thanks.
