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.

Claim (Index 6):
The voltage generating circuit according to  claim 1 , wherein the comparison circuit comprises:\n a second operational amplifier, where a negative input end of the second operational amplifier is coupled to a negative input end or a positive input end of the first operational amplifier, a positive input end of the second operational amplifier receives the reference voltage, and an output end of the second operational amplifier generates the first comparison result; a load, serial connected between the positive input end of the second operational amplifier and a reference ground end, receiving the first current to generate the reference voltage; and a first transistor, where a first end of the first transistor is coupled to a power voltage end, a second end of the first transistor is coupled to the positive input end of the second operational amplifier, a control end of the first transistor receives the first comparison result, wherein the first transistor generates the first current according to the first comparison result.
