Abstract
A feed-forward equalizer includes a shift register, a look-up table circuit, a selection circuit and an output terminal. The shift register temporarily stores and shifts input data based on a clock signal to obtain multiple shifted input data. The look-up table circuit has multiple processed signals. The processed signals are obtained by logical operation of multiple coefficients. An input terminal of the selection circuit is coupled to the look-up table circuit. A control terminal of the selection circuit receives the shifted input data. The selection circuit selects at least one of the processed signals of the look-up table circuit as a selected signal based on the shifted input data. The output terminal provides an output signal according to the selected signal.
