Abstract
A ramp signal generating method and a generator thereof, and a pulse width modulation signal generator are provided. The ramp signal generating method includes following steps: receiving an error signal, wherein the error signal relates to an output voltage of a power converter; generating an error delayed signal according to the error signal; and providing a ramp signal according to the error signal and the error delayed signal. The ramp signal is phase leading and inverting compared to the error signal. The ramp signal serves to improve a response speed of the power converter.
