Pole splitting

Pole splitting is a phenomenon exploited in some forms of frequency compensation used in an electronic amplifier. When a capacitor is introduced between the input and output sides of the amplifier with the intention of moving the pole lowest in frequency to lower frequencies, pole splitting causes the pole next in frequency to move to a higher frequency. This pole movement increases the stability of the amplifier and improves its step response at the cost of decreased speed.
