 Also, I'm not sure I understand how the boost is implemented in the MC servo. It seems like there are no true integrators at all! Instead, the boost switches seem to flip from flat response (up to a few kHz) to a particular pole/zero pair as indicated above that stage on the schematic. What gives?
