Hi guys,
I'm confused, in measuring the power supply rejection of a opamp, which measurement is more important, PSRR or PSR?
PSRR = Differential gain/ Power Supply gain = [Vout/Vin]/[Vout/Vsupply]
PSR = Vout/Vsupply
I'm asking this because some designer say PSR is more important, some say have to see overall PSRR....pls explain.
