Abstract
A voltage converter including a constant turned-on time signal generator, a first transistor, a second transistor, an inductor, a ripple signal compensator, and a ripple injection circuit is provided. The ripple signal compensator is coupled to an output terminal of the voltage converter and a second terminal of the first transistor, and generates an adjusted ripple signal according to a switching voltage on a second terminal of the first transistor and an output signal of the voltage converter. The ripple rejection circuit generates a ripple injection signal according to the adjusted ripple signal. Wherein, the constant turned-on time signal generator generates a first and second driving signals for respectively driving the first and second transistors according to the ripple injection signal.
