Power Supply Rejection Ratio Measurement
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.
