    Abstract: The invention relates to a line driver (3) for conducting data transmissions with high bit rates, particularly for conducting wire-bound data transmissions in the full-duplex method. The line driver comprises a differential pair with differential pair transistors (14, 15) for generating transmit pulses according to the data to be transmitted, whereby the transmit pulses are output to the data transmission line (8, 9), which is connected to the line driver (3), preferably via cascode transistors (16, 17) that respectively form a cascode circuit with the differential pair transistors (14, 15).

    Abstract: An amplifier output stage is described containing a preliminary stage, a final stage and a control device. The quiescent current that flows through transistors of the final stage is adjusted by the preliminary stage. For this, a current that is proportional to the quiescent current is generated in the control device from which control voltages are derived and controlled. The preliminary stage contains adjustable current sources for adjusting the quiescent current in a final step which are controlled by the control voltages.
