Abstract
A reference signal generator used with a switching mode power supply which converts an input voltage to an output voltage. The reference signal generator provides a reference signal consisting of a constant voltage signal and a variable voltage signal which is varying according to a duty cycle of the switching mode power supply during a startup period of the switching mode power supply and is varying according to a ratio of the input voltage at an end of the startup period to the input voltage of real time after the startup period.
