Abstract
A bipolar semiconductor circuit arrangement with transistors of one conduction type having a differential amplifier stage formed by a first and a second transistor with collectors coupled back crosswise to bases thereof and with emitters thereof connected to terminal of a current source having another terminal which is at supply potential, the first and second transistors having a collector circuit wherein a respective resistance is connected includes a pair of control transistors having collector-emitter paths connected between the respective resistances and the collectors of the first and second transistors of the differential amplifier stage, the control transistors having respective base terminals serving as a source of complimentary input signals, and having respective collectors connected to a source of complementary output signals.
