Self-calibrating continuous-time equalization with multiple degrees of freedom

A method for designing self-calibrating continuous-time equalizers is proposed. A pair of error terms, derived from the channel pulse response, may be used to adaptively calibrate the equalizer, resulting in a significant reduction of inter-symbol interference (ISI). Matlab simulations show the clear opening of a twenty Gigabit/second (Gb/s) data eye at the end of a six inch FR4-based signal route.
