Power supplies use control-loop circuits to produce constant voltage or current. The transfer function—gain and phase as a function of frequency—provides valuable information about a control loop’s ...

Did you ever wonder how to calculate the stability of an op amp circuit? Put the wrong compensation network into the feedback loop, and you’re got an attenuator or, worse, an oscillator. It’s not ...

For the PDF version of this article, click here. Switching power supplies rely on feedback control loops to ensure the supply maintains the required voltage and current with varying load conditions.

The two methods for testing DC-DC stability. Frequency behavior with buck VM and CM architectures. Compensators for VM and CM architectures. Aligning the time constants of the LC filter to close the ...
