Zusammenfassung:	A first capacitor is arranged such that the electric potential at a first terminal is fixed. A first discharging circuit discharges the first capacitor at a timing that corresponds to a cyclic synchronization signal received from an external circuit. A first comparator compares the voltage at a second terminal of the first capacitor with a predetermined threshold voltage, and generate a judgment signal that corresponds to the comparison result. A charging circuit generates a charging current the current value of which is adjusted according to the level of the judgment signal at a timing that corresponds to the synchronization signal, and supplies the charging current thus generated to the first capacitor.
