ADAPTIVE CONTINUOUS TIME LINEAR EQUALIZER

摘要

An apparatus comprising an equalizer circuit, a converter circuit and an adaptation circuit. The equalizer circuit may be configured to generate an intermediate signal in response to an input signal and a gradient value. The converter circuit may be configured to generate a digital signal comprising a plurality of symbol values, including a main cursor symbol value, in response to the intermediate signal. The adaptation circuit may be configured to generate the gradient value in response to a plurality of the symbol values before the main cursor symbol value, a plurality of symbol values after the main cursor symbol value, and an error value.
