Apparatus and method for applying dynamic compensation to feedback signal generated from loadline of voltage regulator

A feedback loop circuit of a voltage regulator comprising:

• a loadline, arranged to generate a feedback signal according to a sensed current signal that provides information of an inductor current of the voltage regulator, and output the feedback signal to a controller circuit of the voltage regulator for regulating an output voltage of the voltage regulator;
• and
• a compensation circuit, arranged to generate a compensation signal to compensate for a deviation of the output voltage, wherein in response to a specific event that results in disturbance of the inductor current, the compensation circuit is arranged to make the feedback signal remain unchanged by injecting the compensation signal to the feedback signal generated from the load line.
