Abstract
A method for adjusting a reference voltage is provided, including: decoding a default code configured in a reference voltage register in a chip to obtain an actual reference voltage; comparing the actual reference voltage with a benchmark value to obtain a deviation value between the two; configuring an adjustment code according to the deviation value; and, burning the adjustment code into a nonvolatile storage medium. The present invention also discloses an apparatus for adjusting a reference voltage. Thus, adjustment on the reference voltage of the chip is standardized and costs of the chip's application schemes are saved. A method and apparatus for obtaining a reference voltage are also provided, and thus stability of the circuit's working is improved and costs of the chip's applications are decreased.
