374 Electronic Definition or Meaning for compensating capacitor

Definition for compensating capacitor


What is compensating capacitor in electronics?
Read the following to find out:


compensating capacitor

a capacitor inside an op amp that prevents oscillations. Also, any capacitor that stabilizes an amplifier with a negative-feedback path. Without this capacitor, the amplifier will oscillate. The compensating capacitor produces a low critical frequency and decreases the voltage gain at a rate of 20 dB per decade above the midband. At the unirygain frequency, the phase shift is in the vicinity of 270. When the phase shift reaches 360, the voltage gain is less than 1 and oscillations are impossible.
