<p>An integration circuit includes a differential amplifier constituted by at least two bipolar transistors (11, 12) serving as amplifying elements, a capacitor (17) connected, as a load, to the differential amplifier, and a field-effect transistor (18) having source and drain electrodes connected between the emitter electrodes of the two bipolar transistors. A control voltage is applied to the gate electrode of the field-effect transistor (18). <IMAGE></p> |
