Last time, I teased you about the dark side of op-amp supply current, especially when we’re talking about negative supply pins and how the Single Supply Gang are going around connecting all those pins ...
Read part 1, part 2, and part 3 of this article. The first rule of good EMC design is to eliminate noise at its source. For a switching power supply, which often seems like a natural noise generator, ...
The most common type of power supply today is the switching supply. These units use pulse-width modulation (PWM) to regulate output. Supplies today employ several different PWM circuit configurations.
