A line driver having a non-linear amplifier that is arranged to provide a first
output signal, which is an amplified input signal. The line driver also includes
an analog linear amplifier providing a second output signal based on the difference
between the input signal and the first output signal, placed in parallel with the
non-linear amplifier. The line driver also includes a device to combine the first
output signal and the second output signal to provide a total output signal to
an output line.
