Patent attributes
An embodiment includes a first feedback tap, a second feedback tap, and a summation circuit. The summation circuit may include a first load and a second load coupled to each other at an internal circuit node, and coupled in series between a power supply node and an output node. The summation circuit may be configured to receive, via a serial communication link, an input signal indicative of a series of data symbols, and to generate an output voltage level on the output node based upon a current data symbol. The first feedback tap, coupled to the output node, may be configured to sink a first current from the output node based upon a first previously received data symbol. The second feedback tap, coupled to an intermediate circuit node, may be configured to sink a second current from the intermediate circuit node based upon a second previously received data symbol.
