Abstract
An apparatus comprising an input port configured to receive an input signal propagated through a transmission link, wherein the transmission link comprises a low-frequency channel loss and a high-frequency channel loss, a continuous-time linear equalization (CTLE) circuit coupled to the input port and configured to produce an output signal according to the input signal by applying a first gain to the input signal at a first frequency to compensate the low-frequency loss, and applying a second gain to the input signal at a second frequency to compensate the high-frequency channel loss, and an output port coupled to the CTLE circuit and configured to output the output signal.
