摘要

First, the first charging section C1 charges the parasitic capacitance CS when the switch section is off. Second, the second charging section C2 charges the internal capacitor CD while the switch section SW is kept off. Third, the switch section SW is turned on. Then, charge flows from the internal capacitance CD to the parasitic capacitance CS, and finally the voltage value of the internal capacitance CD becomes equal to the voltage value of the parasitic capacitance CS. Fourth, the switch section SW is turned off, and the second charging section C2 charges the internal capacitor CD again. Thereafter, the voltage value of the parasitic capacitance CS can be set to a desired value by repeating the third and fourth steps.
