PSRR for Opamp and Voltage References

PSRR is an important parameter to measure for Opamp and votage references.

PSRR is a significant performance concern as even small

amounts of high frequency ripple voltage at the input can significantly degrade the output

precision of voltage reference and impact

downstream circuitry. The output of the Op Amp is not only a function of the inputs, but also of the power supply.
