Capacitance charging current limitation a direction, charge pump configuration, a method for limiting a charging current to a charge pump and a method for limiting of the charging current to a condenser

摘要

It is a capacitor charging current limitation a direction with a differentiating device is provided, which are parallel to a node to a charging capacitor is connected to be charged. It is a switching device, which is connected to an output of the differentiating device, is provided, wherein said switching means comprises a charging current supplied to the capacitor, when at the output of the differentiating device a predetermined value.
