Abstract
A feedback circuit of a voltage regulator with adaptive voltage positioning (AVP) includes a first sensing circuit, a second sensing circuit, a third sensing circuit, and a processing circuit. The first sensing circuit generates a first feedback signal that provides information of an inductor current of the voltage regulator. The second sensing circuit generates a second feedback signal that provides information of an output voltage of the voltage regulator. The third sensing circuit generates a third feedback signal that provides information of a capacitor current of an output capacitor of the voltage regulator. The processing circuit generates a control voltage signal according to the first feedback signal, the second feedback signal, and the third feedback signal, and outputs the control voltage signal to a controller circuit of the voltage regulator for regulating the output voltage of the voltage regulator.
