  • Patent number: 7084677
    Abstract: The invention relates to a line driver arrangement for driving signals via at least one subscriber line, provided with: an input for injecting an input signal and having an output at which a signal which is to be driven via the subscriber line can be tapped off, a digital amplifier which produces a pulse-width-modulated signal on the output side from the input signal or from a signal derived from it, an analog amplifier, which produces an analog signal on the output side from the input signal or from a signal derived from it, with the outputs of the amplifiers being coupled such that the signal to be driven results from superimposition of the analog signal and the digital signal, with the gain of the analog amplifier being matched to the gain of the digital amplifier such that scatter and/or overshoot on the digital signal are at least reduced after the superimposition.

  • Patent number: 6937721
    Abstract: Broadband driver circuit for driving voice and data signals, having a current dividing circuit (37), which divides a current generated by a current source (38), in a manner dependent on a voice and data signal present at a signal input (21), into two base currents (Ib1, Ib2) for driving a first driver transistor (39) and a second driver transistor (40), the two driver transistors (39, 40) being constructed identically.
