Abstract: A charge amplifier circuit includes an operational amplifier with an integrating capacitor between its inverting input and its output, and a resetting device with a switch that is closed during the reset phase for discharging the integrating capacitor. Provided at the output of the charge amplifier circuit is a circuit arrangement with a correction amplifier which when the switch is closed, automatically delivers a correction charge to the integrating capacitor, compensating the zero shift of the output voltage from the charge amplifier circuit during the measuring phase. This circuit arrangement is particularly suited for charge amplifiers with an extremely high ohmic input stage.
