Abstract
A reference voltage generation circuit for generating an output voltage is provided. The reference voltage generation circuit includes a bandgap reference circuit and a voltage adjustment circuit. The bandgap reference circuit generates the output voltage at an output node and a reference voltage. The voltage adjustment circuit is coupled to the bandgap reference circuit. The voltage adjustment circuit receives the output voltage and the reference voltage, compares the output voltage with the reference voltage to generate a comparison result, and adjusts the output voltage according to the comparison result.
