Patent ID: 7916779

Claim:
A receiver comprising: an adaptive decision feedback equalizer comprising: a filter module configured to receive a first serial data signal and to generate a filtered signal by reducing inter-symbol interference in the first serial data signal; a compensation module configured to generate a compensated signal comprising serial data by equalizing amplitudes of frequency components of the filtered signal in a compensation frequency range to reduce inter-symbol interference in the filtered signal, the compensation module including: an amplifier configured to generate an amplified signal by amplifying the filtered signal; an amplitude limiter configured to generate an amplitude limited signal by limiting amplitudes of frequency components of the amplified signal in the compensation frequency range; and a low pass filter configured to generate the compensated signal by reducing frequency components of the amplitude limited signal having frequencies above the compensation frequency range; and a slicer module configured to generate a second serial data signal by determining at least one logic state of the compensated signal; and a deserializer configured to generate a parallel data signal comprising parallel data by converting serial data of the second serial data signal to the parallel data.
