DECISION-FEEDBACK EQUALIZER

摘要

A decision-feedback equalizer for use in a receiver unit for receiving an incoming data stream and for providing a stream of bit data outputs includes a plurality of asynchronous comparators and a fastest decision detector unit operatively coupled with the asynchronous comparators. Each of the asynchronous comparators is configured to receive an input signal and to directly provide a comparison result output in an asynchronous manner. The fastest decision detector unit is configured for receiving at least a subset of the respective comparison result outputs of the asynchronous comparators and for forwarding the comparison result of one of the asynchronous comparators towards the output of the decision-feedback equalizer. The fastest decision detector unit is configured to select a given one of the asynchronous comparators as one which firstly provided its comparison result output.
