Abstract
A voltage generating circuit includes a first comparator, a boost circuit, a second comparator and an output circuit. The first comparator compares a first reference voltage with a first feedback voltage generated based on a first output node, and generates a first control signal accordingly. The boost circuit is controlled by the first control signal to output a boost voltage to the first output node. The second comparator compares a second reference voltage with a second feedback voltage generated based on a second output node, and generates a second control signal accordingly. The output circuit receives the boost voltage, and is controlled by the second control signal to convert the boost voltage into a drive voltage and output it to the second output node. The boost voltage is determined by the first reference voltage, the drive voltage is determined by the second reference voltage.
