I still think what I described is reasonable (you Italians just like to argue
)
There may be some strict definitions of proper zero / poles definitions which I have long forgotten, especially dealing with zeros in the feedback.
As I see it this capacitor forms a zero in the feedback path, that is it increases the amount of feedback (less attenuation of the output).
I was simplifying by considering the feedback path as part of the open loop gain where then the capacitor forms a zero then a pole with its smaller series resistor.
Conversely, you can on a bode plot, put this zero in the feedback (which is drawin the same as a pole in the OLG, maybe thats the source of our different points of view).
Just kidding about Italians
yes my last name ends with an I
