WebMay 24, 2006 · A simple circuit technique is presented for improving poor midband power supply rejection ratio (PSRR) of single ended amplifiers that use Miller capacitance to set the location of the dominant pole. The principle of the technique is to create an additional parallel signal path from the power supply to the output, which cancels the dominating … Webpower supply rejection ratio (PSRR). For an amplifier, PSRR is the ratio of the change in output voltage to the change in power supply voltage, expressed as a ratio (PSRR) or in dB (PSR). PSRR can be referred to the output (RTO) or referred to the input (RTI). The RTI value is equal to the RTO value divided by the gain of the amplifier.
WebPSRR is the ratio of the change in input offset voltage with respect to the change in power supply voltage. The standard used in the datasheet is DC Variation. PSRR=20log (Power Supply Variation)/ (Input Offset Voltage Variation) [dB]. Generally, PSRR is frequency dependent, and decreases as the frequency increases.
