Line drivers with extended linearity are described herein. In one embodiment, an example of a line driver includes, but is not limited to, a first amplifier having a first input, a second amplifier having a second input, the first and second amplifiers driving a load of a communication line, and a trans-conductance stage device coupled to the first and second amplifiers. The trans-conductance stage device is configured to sense a first error voltage across the first input of the first amplifier and to provide a first feedback to the second input of the second amplifier. The trans-conductance stage device is configured to sense a second error voltage across the second input of the second amplifier and to provide a second feedback to the first input of the first amplifier. Other methods and apparatuses are also described.
