Abstract
A decision-feedback equalizer for use in a receiving unit of an incoming data stream and for providing a stream of bit data outputs includes a number of comparators configured to perform a comparison related to a number of threshold values and related to a digitalized data sample and to obtain a comparison result; at least one correction block configured to receive the comparison result of a respective one of the comparators and to generate a plurality of intermediate results; and a multiplexer configured to select from the set of intermediate results depending on the output data history to provide the stream of bit data outputs.

A decision-feedback equalizer for use in a receiving unit of an incoming data stream and for providing a stream of bit data outputs, comprising:
- a number of comparators configured to perform a comparison related to a number of threshold values and related to a digitalized data sample and to obtain a comparison result;
- at least one correction block configured to receive the comparison result of a respective one of the comparators and to generate a plurality of intermediate results;
- a multiplexer configured to select from the set of intermediate results depending on an output data history to provide the stream of bit data outputs;
- and
- a threshold value memory configured to supply the threshold values, wherein at least one of the threshold values is associated to a plurality of patterns of the output data history.
