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 ...

With the introduction of commercially available amplifiers using the current feedback topology by Comlinear Corporation in the early 1980’s, previously unattainable gain and bandwidths in a DC coupled ...

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.
