What is dominant pole frequency?

The lowest frequency pole is called the dominant pole because it dominates the effect of all of the higher frequency poles.

What is dominant pole in opamp?

This circuit is called dominant-pole compensation because if the pole formed by the op amp output impedance and the loading capacitor is located close to the zero frequency axis, it becomes dominant. The op amp circuit is shown in Fig. 8.8, and the open-loop circuit used to calculate the loop gain (Aβ) is shown in Fig.

What is pole zero compensation?

In order to maintain the regulator stability and performance over wide load current range, a novel pole-zero tracking frequency compensation scheme is proposed. Using a backing zero to cancel the output pole, the frequency response becomes load current independent.

What is meant by frequency compensation?

Op-Amp Frequency Compensation

Typically, the compensation is intended for closed-loop gains all the way down to the unity gain of voltage-follower operation. A subclass of op-amps come compensated for closed-loop gains above a value greater than unity, such as 10 V/V.
