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 ...

You can purchase test equipment that will allow you to examine the loop gain and loop phase properties of an operating feedback loop and, that purchased equipment will deliver useful results over a ...

In operational amplifier stability, one rule of thumb is to allow 45 degrees of phase margin. Other design guidelines state that 60 degrees is best; still others say that 30 degrees is sufficient.
