Disclosed are a Pulse Width Modulation (PWM) generation circuit, a processing circuit and a chip. The PWM generation circuit is used for controlling a rotation speed of an external motor system. The PWM generation circuit includes a second clock prescaler and a PWM signal generator. A frequency division output end of the second clock prescaler is connected to a data input end of the PWM signal generator. The PWM signal generator includes an output frequency divider and a comparator. A clock output end of the output frequency divider is connected to a comparison input end of the comparator. By means of the technical solution, PWM signals with different duty ratios.

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.
