Power Supply Rejection Ratio (PSRR) in RF Circuit Designs

Power Supply Rejection Ratio (PSRR) in RF Circuit Designs

Is it Power Supply Rejection Ratio, Power Supply Ripple Rejection, or Supply Ripple? Yes! PSRR (Power Supply Rejection Ratio) is all three! Power Supply Rejection Ratio is also referred to as Power Supply Ripple Rejection, but in the world of timing solutions, we typically take the simple route and refer to PSRR as supply ripple. In this post, we will use both terms, PSRR and supply ripple, interchangeably.

PSRR is a measure of how well a circuit rejects noise of various frequencies from a particular device’s power supply. More specifically, from a device’s voltage input. Optimally, if the voltage input of a device changes, the output should not change. Unfo...
