Abstract
A method for performing loop unrolled decision feedback equalization (DFE) and an associated apparatus are provided. The method includes: receiving a tap control signal and an offset control signal from a digital domain of a DFE receiver in an electronic device, and generating DFE information respectively corresponding to the tap control signal and the offset control signal in an analog domain of the DFE receiver; broadcasting the DFE information respectively corresponding to the tap control signal and the offset control signal toward comparators in the DFE receiver; utilizing the comparators to perform comparison operations according to the DFE information respectively corresponding to the tap control signal and the offset control signal to generate comparison results; and selectively adjusting the tap control signal and the offset control signal according to the comparison results, to optimize the DFE information respectively corresponding to the tap control signal and the offset control signal, respectively.
