Power Supply Rejection Ratio
... In electronics, power supply rejection ratio or PSRR is a term widely used in the electronic amplifier (especially operational amplifier) or voltage regulator datasheets used to describe the amount of noise from a ... The PSRR is defined as the ratio of the change in supply voltage to the equivalent (differential) input voltage it produces in the op-amp, often expressed in decibels ... An ideal op-amp would have infinite PSRR ...
