ABSTRACT:
Embodiments of the invention are generally directed to a high-speed differential energy difference integrator (EDI) for adaptive equalizers. In an embodiment, the EDI includes two differential full-wave rectifiers providing differential outputs that are cross-coupled to the inputs of an integration capacitor. In one embodiment, the active areas of the transistors of the differential full-wave rectifiers are substantially the same.
