When testing the stability of a switched-mode power supply, a Bode plot by an oscilloscope is ideal for checking the critical phase margin and gain margin values. This guide provides practical tips on ...
Analytical approach demonstrates how the open-loop gain and phase prediction can determine the optimal compensation network for a zero current switched (ZCS) dc-dc, variable frequency forward ...
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.
