Abstract

See full text

A decision-feedback equalizer for use in a receiving unit for receiving an incoming data stream and for providing a stream of bit data outputs, including at least one decision-feedback equalizer block comprising a plurality of speculation units. Each speculation unit includes a dynamic preamplifier for asynchronously amplifying a voltage difference depending on an input voltage of the incoming data stream and a given threshold voltage; and an arrangement for selectively generating a transconductor current which depends on the amplified voltage difference. Also included is one dynamic regenerator for associating an output data bit to the selectively generated transconductor current.
