Frequency compensation
Parameter ζ is set by a compensation capacitor: smaller ζ results in faster response, but more ringing and overshoot. Most amplifiers use negative feedback to trade gain for other desirable properties, such as decreased distortion, improved noise reduction or increased invariance to variation of parameters such as temperature.
