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 (usually an input pole) to lower frequencies, pole splitting causes the pole next in frequency (usually an output pole) 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.

Property Value
dbo:abstract
  • 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 (usually an input pole) to lower frequencies, pole splitting causes the pole next in frequency (usually an output pole) 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. (en)
  • 極點分離(Pole splitting)是在放大器電路中進行頻率補償時,可能會出現的現象。若在放大器的輸入側和輸出側加上电容器,希望將最低頻率的极点(多半在輸入側)時,極點分離會使次低的極點頻率提高。此極點的移動會提昇放大器的穩定性,也會改善其階躍響應,但其速度會變慢。 (zh)
