Abstract
A linear feedback equalizer includes comparators that digitize incoming analog signals. The equalizer further includes digital-to-analog converters ('DACs') that transform a current digitized signal into one or more feedback analog signals. The equalizer further includes a subtractor that subtracts the feedback analog signals from the output of a continuous-time linear equalizer ('CTLE') and provides the difference to the comparators as incoming analog signals.
