An amplifier’s PSRR (power-supply-rejection ratio) is among the most commonly characterized parameters when analyzing the performance of an op amp. Examples of some noise sources on an amplifier’s ...
Previous installments of this series discussed the need to verify SPICE model accuracy and how to measure the output impedance and small-signal bandwidth of operational amplifier (op amp) models. In ...
This white paper discusses a method for driving high-frequency sinusoidal ripple over capacitive loads for power supply rejection ratio (PSRR) testing, an important performance parameter for many ...
Earlier this month Power Electronics received a question about "How to measure PSRR of a linear regulator circuit that powers an oscillator for an ADC. How can I make this measurement using my ...
Low-dropout (LDO) linear regulators have been widely used in noise-sensitive applications for decades. Nevertheless, noise requirements have become tougher to meet as the latest precision sensors, ...
