Abstract

A capacitance measurement device for measuring the capacitance of a measured capacitor includes a charging control unit for charging the measured capacitor; a discharging control unit for discharging the measured capacitor; a voltage converting circuit coupled to the measured capacitor, for converting a voltage signal on the measured capacitor into a value that represents the capacitance of the measured capacitor; wherein in a first period, one of the charging control unit and the discharge control unit charges/discharges the measured capacitor and in a second period after the first period, the other one of the charging control unit and the discharge control unit discharges/charges the measured capacitor.
