摘要： The present disclosure relates to a method and a device for measuring a force action. The disclosure additionally relates to an input apparatus which uses such a device or such a method. In a first step, a voltage pulse resulting from a force action on a force sensor is generated by a charge amplifier. Using this voltage pulse, a trigger pulse may be generated by a comparator circuit. A voltage value derived from the voltage pulse is then stored in a storage capacitor by a current mirror. The capacitor voltage resulting therefrom may be evaluated by an evaluation unit.
