Abstract
The present disclosure relates to a floating tap, partially rolled digital feedback equalization circuit and method of using the same. The circuit may include an analog front end circuit and a digital circuit in electrical communication with the analog front end circuit, wherein the analog front end circuit includes a first unrolled tap and a plurality of rolled taps.
Claims18
A floating tap partially rolled digital feedback equalization circuit comprising:
- an analog front end circuit;
- a digital circuit in electrical communication with the analog front end circuit, wherein the analog front end circuit includes a first unrolled tap and a plurality of rolled taps;
- and
- an interleaved structure configured to allow data sampling using a rising and a falling edge of a sampling clock, wherein the interleaved structure received data from two separate receivers associated with one or more equalizer taps that are associated with one or more of the first unrolled tap and the plurality of rolled taps.
