1. Circuit arrangement for a Low Voltage Differential Signal (LVDS) driver, which uses combined bipolar and MOSFET technology with at least two MOSFETs, wherein a multiplier circuit is connected to an output stage of the LVDS driver and the multiplier circuit is controlled by means of an automatic control circuit, which generates control signals for controlling a current source of the multiplier circuit and for controlling the amplification factor of differential input signals of the multiplier circuit.
