Abstract
A pipelined decision feedback equalizer (DFE) includes a programmable digital-to-analog converter (DAC) configured to provide a programmable voltage to a plurality of decision feedback equalized (DFE) sections, a capacitive element associated with each DFE section, the capacitive element coupled to an input connection by a first switch and coupled to an output connection by a second switch, clock logic configured to control the first switch and the second switch so that a predefined voltage signal is applied to the capacitive element at a predefined time such that a charge corresponding to the predefined voltage signal is applied to the capacitive element, the clock logic causing the second switch to couple the capacitive element to the output connection so as to apply the voltage on the capacitive element as a filter coefficient to a summing element.
