Even the simple circuit of Figure 1 seems to be suffering from a low phase margin condition as described in Reference 1 with a sharp resonance at 165MHz. It is important, even in lower speed signal ...

Looking at the amplifier circuit shown in Figure 1, one could estimate how stable it is by determining the phase shift encountered when the signal goes around the loop one time, while the loop is ...

It’s impossible to directly measure the stability (gain/phase) characteristics of a device if the device’s control loop lacks an access point to apply a test signal or can’t be broken. For many of ...
