I designed a system to convert from 1.8V to 3.3V. I have the schematic diagram as shown below.
I am running corner analysis and it passes all the corners except in SS_pre as shown below. I get ripples. When I see the switching of the comparator is slow. From what I can see either it is slow from the voltage divider to the input of comparator or the comparator itself is slow. Can anyone suggest how can I find the which of the two is causing me the problem?
