Newbie level 3
I need a high performance integrator.
And I want to check 'Stability of the integrator block'.
So I designed it like the figure, and assigned it as the STB instance of SPECTRE at the place labeled VAC and simulated it.
Loop gain and phase margin are shown in the figure.
The area marked in red has a gain greater than 0dB.
Should I only get the "phase margin" in red?
If not, how should we check it?
If you have any good documents, please share them.
