Abstract
A multi-phase voltage regulator is coupled to a multi-phase DC-DC converter and comprises multiple voltage regulator circuits. The voltage regulator circuit is coupled between a power output stage circuit and a compensation circuit, and is configured to generate multiple control signals according to a compensation signal, so that the power output stage circuit generates multiple output currents. The voltage regulator circuit comprises a current comparison circuit and a delay circuit. The current comparison circuit is configured to obtain a error signal. The error signal is the difference between a threshold current and the corresponding output current. The delay circuit is is configured to generate a corresponding control signal according to the compensation signal. The delay circuit is configured to adjust a bias current in the delay circuit according to the error signal to adjust a duty cycle of the corresponding control signal.
