WebNoise Sources A typical power supply consists of an AC/DC rectification stage followed by a high frequency DC/DC stage and control circuitry to regulate the output voltage. Noise from the power supply mainly originates from the switching power semiconductors. Switch mode power supplies are much more efficient, smaller and more economical than ... WebPower Supply Rejection Ratio or Power Supply Ripple Rejection (PSRR) is a measure of a circuit’s power supply’s rejection expressed as a log ratio of output noise to input noise. PSRR provides a measure of how well a circuit rejects ripple, of various frequencies, injected at its input. The ripple can be either from
