Abstract
A voltage converter is provided. The voltage converter includes a compensation circuit, a first comparator circuit, a first inductor, a first driver circuit, and a phase-lag circuit. The compensation circuit generates a first compensation signal according to a loading state of the voltage converter. The first comparator circuit compares the first compensation signal and a first reference signal to generate a first comparison signal. The first driver circuit generates a first driving voltage to the first inductor according to the first comparison signal. The phase-lag circuit is coupled between the first comparison circuit and the first driver. The phase-lag circuit modifies a duty of the first comparison signal for changing a first inductor current following the first inductor.
