A high speed CMOS-implemented equalizer architecture as described herein
utilizes a digitally controlled analog equalization scheme to equalize
intersymbol interference present in an input signal. The equalizer
structure includes an inductor high frequency gain boosting stage and a
feed forward high frequency equalizer stage connected in series. The
equalization performed by each of these gain boosting stages is
controlled by one or more digital control signals. The combination of
these stages results in the equalization of both amplitude and phase
distortion. The equalizer architecture is suitable for use with
communication systems that operate at 11.2 Gbps speeds.
