WebPower Supply Rejection Ratio or Power Supply Ripple Rejection (PSRR) is a measure of a circuit’s power supply’s rejection expressed as a log ratio of output noise to input noise. PSRR provides a measure of how well a circuit rejects ripple, of various frequencies, injected at its input. The ripple can be either from In electronic systems, power supply rejection ratio (PSRR), also supply-voltage rejection ratio (kSVR; SVR), is a term widely used to describe the capability of an electronic circuit to suppress any power supply variations to its output signal. In the specifications of operational amplifiers, the PSRR is defined as the ratio of the change in supply voltage to the equivalent (differential) output voltage it produces, often expressed in decib…
