WebJan 6, 2011 · I am simulating the AC response of a unity-gain feedback amplifier using Spectre stb analysis. It works fine for most corners. But for some corners such as slow-fast (t=-40,125; vdda=2.05), the loop phase suddenly change to 0 degree at DC (it's supposed to be 180 degree). That means positive feedback! It's so werid.
