ABSTRACT:
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.
