Patent ID: 7983333

Claim:
A non-linear decision feedback equalizer, comprising: a summation network configured to combine a weighted output with an input to provide an equalized output; a slicer module configured to digitize the equalized output according to a threshold to provide a slicer output; a delay module configured to delay the slicer output to provide a delayed slicer output; a first multiplier configured to multiply the delayed slicer output by a first equalization coefficient characterized as having a first magnitude to provide a first logic weighted output; a second multiplier configured to multiply the delayed slicer output by a second equalization coefficient characterized as having a second magnitude to provide a second logic weighted output, the second magnitude being different from the first magnitude; and a switch configured to select between the first logic weighted output and the second logic weighted output based upon a logic level of the delayed slicer output to provide the weighted output.
