I have a question regarding the frequency response of a boost converter. I am curious to know what causes the "blip" at around 8kHz that causes the response to go up and then back down. At first, I thought that perhaps it may be a ESR zero, but thinking more closely, a single zero would not cause the response to rise like that. Furthermore, the response shows another pole afterwards, and I can't quite see where its coming from either. Anybody experience this or seen the cause of this before?
