FEEDBACK IMPEDANCE CONTROL FOR DRIVING A SIGNAL

摘要

A system for driving a first signal onto a wireline includes a driver and feedback circuitry. The driver drives a deterministic signal onto the wireline with an unknown impedance load. The feedback circuitry measures a quality of the output signal from the wireline and modifies a gain of the first signal based on the quality of the output signal. The driver then drives the first signal onto the wireline with the modified gain.
