Hi team,
My customer recently met the stability issue.
I try to help to analyze the phase margin.
Could you please help to check whether my setting is right?
Schematic:
Loop1:
Loop2:
If the setting is right and good simulated phase margin, what is the reason that customer's waveform looks bad.
Could you please help to give some suggestions?
Thanks!
