摘要： A non-linear load driving circuit and a controller for controlling a conversion circuit to drive a non-linear load are provided. The controller includes a feedback unit, a pulse width control unit, and an overshoot reduction unit. The feedback unit generates a feedback signal according to a current feedback signal that represents a load current flowing through the non-linear load. The pulse width control unit generates a control signal according to the feedback signal to control a power output of the conversion circuit. The overshoot reduction unit generates an overshoot reduction signal when the load current changes from being smaller than to being greater than a predetermined value according to the current feedback signal. The pulse width control unit receives the overshoot reduction signal and reduces the duty cycle of the control signal accordingly. Thereby, stability of feedback control is improved and damage to circuit is prevented.

摘要： The invention relates to an analog-to-digital converter comprising a reference voltage generating circuit, two coarse/fine comparators and two encoders for encoding the comparison result of the two coarse/fine comparators. In the invention, the two coarse/fine comparators processes a coarse comparison procedure and a fine comparison procedure on an input voltage in different clock cycle, thus, a sampling voltage error caused by an error of sampling time decreases. In another aspect of the invention, the capacitance of the input capacitor of the analog-to-digital converter decreases because the comparators for coarse comparison and fine comparison are the same, thus, a large power amplifier is not required for driving the input capacitor.
