I have addressed this topic before, but we’ll take a little deeper look at it this time. First off, we are not going to discuss the loop gain situation of Figure 1, even though trying to cope with a ...

We have learned, courtesy of Dean Venable, the following method of measuring loop gain, typically in a switchmode power supply, but elsewhere too: A test signal, here called “es”, is injected where ...

Switching power supplies rely on feedback control loops to ensure that the required voltage and current are maintained under varying load conditions. Design of the feedback control loop influences ...
