The amount of over-shoot is intriguing too. I made a Class D amp back in 1988 for my degree - the 'carrier' was at 'only' at 200Khz. I'm not sure though if I got this much over-shoot?, cause by a little too much inductance and capacitance (effectively a second, third order system?), which may be difficult to dampen nail, and so dampen? I really must go and look at my old 1988 report. :o) BTW, thanks for these videos!!!

Thanks very much for taking time to make these lessons. You seem to really know this stuff! Dig it
how pwm is amplified? ,is it done by the comparator, or the output mosfet? but the two mosfet is configured like a buffer in class ab amplifier
Very nice
