Abstract: The invention provides a feedback control device and a feedback control method thereof. The feedback control device includes an enhancing circuit and a comparator. The enhancing circuit receives a feedback voltage corresponding to an output voltage of a DC-to-DC converter. In an embodiment, the enhancing circuit generates an enhanced feedback voltage based on the feedback voltage, and the comparator uses a comparison result between a reference voltage and the enhanced feedback voltage as a control signal to a feedback control terminal of the DC-to-DC converter. In another embodiment, the enhancing circuit generates an enhanced reference voltage based on the reference voltage, and the comparator uses a comparison result between the enhanced reference voltage and the feedback voltage as the control signal. In yet another embodiment, the comparator uses a comparison result between the enhanced reference voltage and the enhanced feedback voltage as the control signal.

Abstract: A voltage generating circuit including a pre-driving unit and a voltage generating unit is provided. The pre-driving unit receives an oscillation signal and enhances a driving capability of the oscillation signal to generate a pre-driving signal. The voltage generating unit receives an input signal and the pre-driving signal, and generates an output signal according to the input signal and the pre-driving signal. The voltage generating unit generates a voltage signal according to the pre-driving signal. One of the pre-driving unit and the voltage generating unit adjusts a slew rate or a ringing component of the voltage signal by using the pre-driving signal. A pre-driving signal generating module for driving a voltage generating circuit is also provided.
