Abstract:
In a voltage generating circuit, a bandgap voltage generator has a first operational amplifier to receive a first voltage and a second voltage, and generate a bias voltage by comparing the first voltage and the second voltage, wherein the bandgap voltage generator generates a bandgap current according to the bias voltage and generates an output voltage according to the bandgap current. In a start-up circuit, a comparison circuit compares the first voltage or the second voltage with a reference voltage to generate a first comparison result, and generates a first current according to the first comparison result. A voltage regulator generates a second current according to the first current, and compares the second current with a reference current to generate a second comparison result, and adjusts a voltage value of the bias voltage according to the second comparison result.
