Abstract: A method and an apparatus for determining resistance values of a dynamic voltage-adjusting circuit are provided. The method includes determining a reference voltage, a maximum output voltage value, and a minimum output voltage value of the dynamic voltage-adjusting circuit; determining, according to the reference voltage, the maximum output voltage value and the minimum output voltage value, a first relational expression between the reference voltage, the maximum output voltage value, and multiple resistors of the dynamic voltage-adjusting circuit, and a second relational expression between the reference voltage, the minimum output voltage value, and the multiple resistors; and determining a group of resistance values of the multiple resistors according to the two relational expressions. It is ensured that voltage values output by the dynamic voltage-adjusting circuit can fall within a same range when the reference voltage takes different values.
