Method and electronic device for generating a reference voltage

Abstract

A method for generating a reference voltage is provided. The method for generating a reference voltage includes the following steps: providing a voltage identification signal corresponding to an operating frequency of a processor; receiving the voltage identification signal and providing a reference voltage according to the operating frequency; determining whether the reference voltage is greater than a first threshold voltage or less than a second threshold voltage; regulating the reference voltage corresponding to the voltage identification signal by adding a first offset voltage when the reference voltage is greater than the first threshold voltage; and regulating the reference voltage corresponding to the voltage identification signal by subtracting a second offset voltage when the reference voltage is less than the second threshold voltage. In addition, an electronic device using the method for generating a reference voltage is also provided.
