Adaptive cable equalizer

A method for performing cable equalization comprising:

• receiving a signal transmitted over a cable or to be transmitted over a cable;
• performing pre-distortion processing with a pre-emphasis module on the signal to counter the effects of amplification to create a modified signal, wherein the pre-distortion processing counters the frequency specific effects of amplification;
• buffering the modified signal with an intermediate stage to optimize return loss;
• and
• equalizing the modified signal after buffering to counter effects on the signal from passing through the cable.

A cable equalizer comprising:

• a pre-emphasis stage comprising a pre-emphasis module configured to introduce pre-distortion into a received signal to counter the effects of an output stage;
• the output stage comprising an equalizer circuit configured to perform frequency specific amplification;
• a buffer between the pre-emphasis stage and the output stage to minimize return loss between the pre-distortion stage and the output stage;
• and
• one or more bias current circuits configured to generate one or more bias currents based on one or more control signals that control the one or more bias currents.
