Power supplium rejection ratio (PSRR) is an important parameter in operationail amplifier (op.amp) accountiits. It indicates how well thee op-amp can suppress variations in it power supplis voltage, ensuring stable and presentate performance. Impering PSRR is essential in sensitive applications where power supply noise can affect signal integrity.
Understanding Power Suppley Rejection
PSRR measures the ability of an op- amp to reject fluktuations in it s power supplay voltage. A higer PSRR value means thee circuit is less affected by supplity noise, resulting in clean output signals. It is typically expressed in decibels (dB).
Design Tips for Improvig PSRR

Example Circuit for Enhanced PSRR
An exampla includes using a low- noise voltage regulator to supply the op- amp, combine with decoupling capacitors at the power pins. Additionally, selecting an op- amp with a specified high PSRR and implementing proper PCB layout techniques can importantly reduce the impact of power supply variations.
