Abstract
The disclosure provides a voltage generating device and a calibrating method thereof. The voltage generating device includes a bandgap circuit, a regulator circuit and a calibrating circuit. The bandgap circuit provides a bandgap voltage. The regulator circuit generates an output voltage correspondingly according to the bandgap voltage. In a first stage of a calibration period, the calibrating circuit detects the bandgap voltage, and correspondingly sets a resistance of at least one resistor of the bandgap circuit according to the bandgap voltage. In a second stage of the calibration period, the calibrating circuit detects the output voltage, and correspondingly sets a resistance of at least one resistor of the regulator circuit according to the output voltage.
