Measuring Switching Regulator Noise

Jim Williams - Applications Guru Jun 15th 2009
The universal application of switching regulators, combined with the powered systems potential for supply noise sensitivity, mandates the need for a reliable noise measurement technique. Actually, switching regulator "noise" isn't really noise at all, but coherent, high frequency residue directly related to the regulators switching. ...

How To Build a Low Noise Power Supply for High Voltage (i.e. 100V up to 1000V) Transducers

Jim Williams - Applications Guru Sep 15th 2008
A Kilovolt with 100 Microvolts of Noise Photomultipliers (PMT), avalanche photodiodes (APD), ultrasonic transducers, capacitance microphones, radiation detectors and similar devices require high voltage, low current bias. Additionally, the high voltage must be pristinely free of noise; well under a millivolt is a common ...
