Frequency compensation
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. Ideally, the phase characteristic of an amplifier''s frequency response would be linear; however, device limitations make this goal physically unattainable. More particularly, capacitances within t…
