Zusammenfassung:	In an integration circuit including an operational amplifier wherein an integrating capacitor and a switch are connected in series across the operational amplifier as a negative feedback circuit, a positive feedback resistor is connected between the connecting point between the integrating capacitor and the switch and the reference input terminal of the operational amplifier. The potential difference across the integrating capacitor is made zero in order to remove the influence of the leakage current of the switch when the switch is in its OFF-state.
