Abstract
Systems and methods disclosed herein provide for reducing noise on an data signal at receiving devices. Systems and methods disclosed herein are suited for opening a data eye by reducing noise, such as inter-symbol interference. An example of the systems and methods disclosed herein include a first equalization circuit that receives an input data signal and applies amplification to the input data signal, and a second equalization that adjusts a first pulse of the first compensated data signal based on a subset of pulses that preceded the first pulse in the first compensated data signal. In an illustrative example, the first equalization circuit can be provided as a continuous time linear equalization (CTLE) that apply a fixed boost and adjustable gain to the input data signal, and the second equalization circuit can be provided as a multi-path decision feedback equalization (DFE).
