About the overshoot
When the amp's some transistors work in the non-saturation region, and the amp is connected as unity gain buffer, when input small pulse, the output will appears overshoot and ringing, why it is so? Does the phase margin reduce? If it is so, how can the low gain influence the poles and zeros?
Hopefully you can give me intruction more detail, perhaps using the 7 transistor to demonstrate will be clearer. Thank you ahead.
