Power supply, method for voltage compensation and electronic device

Abstract

A power supply, method for voltage compensation and electronic device are provided. The power supply includes: a plurality of temperature compensation modules, for providing a plurality of reference voltages respectively based on a plurality of temperature curves which are not identical, and each of the temperature curve linearly characterizing a corresponding relationship between the reference voltage and temperature in a plurality of temperature ranges respectively; and a summation module, for providing an output voltage in accordance with the plurality of reference voltages, wherein for at least one temperature curve, at least two temperature ranges correspond to different temperature coefficients, so that an output voltage curve characterizing the output voltage changing with temperature has not identical temperature coefficients at least in two temperature ranges, and a critical temperature between temperature ranges in the output voltage curve corresponds to a stable output voltage.
