In a Close loop circuits, we can test any node for frequency response for stability.
like Figure 1. If out node show a peak, the circuits will oscillate.
So If any one show a peak besides in and out nodes , and out node shows good
phase margin , is this circuits stable ?
I think we must set all node have a good phase margin, to ensure the circuits will
not oscillate. Is it right.

right.
生平最BS没事说鸟语
学习一下
BS是国语?学好英语对IC来说挺重要的，不要总是一副卫道士的嘴脸
人家说鸟语的就是比你牛。比别人菜只有被别人bs的资格。
Based on the state-variable control theory, yes, you have to make sure all nodes are stable.
yeah, all nodes must be stable
stability is very important
important for system not to osc
