Abstract:
A voltage regulator calibration circuit including a voltage regulator and a calibration unit is provided. The voltage regulator regulates an output voltage according to a reference voltage and a feedback voltage. The feedback voltage is in direct proportion to the output voltage. The calibration unit is coupled to the voltage regulator. The calibration unit generates a control code through binary search according to the output voltage and a target voltage. The control code determines the proportion of the feedback voltage to the output voltage.
