I'd like to know what is important when checking the phase margin and gain margin, and standard values for margins.
- For the phase margin, the phase at the frequency at which the gain is 0 dB is measured, and for the gain margin, the gain at the frequency at which the phase is 0 degrees is determined, and the margins for each of these are studied. Representative values are 45 degrees or greater for the phase margin, and for the gain margin, -10 dB or lower.
