Abstract

A high bandwidth continuous time linear equalization (HBCTLE) circuit is disclosed. The HBCTLE circuit includes a continuous time linear equalization (CTLE) circuit and a gain circuit coupled with an output of the CTLE circuit. A feedback circuit is coupled between the output of the CTLE circuit and an output of the gain circuit.

Description

technical field [0001] The present invention relates to high bandwidth continuous time linear equalization circuits. Background technique [0002] Wired communication refers to the transmission of data via wire-based communication techniques. In general, wireline communication is considered the most stable of all types of communication services. Such as Universal Serial Bus (USB), High Definition Multimedia Interface (HDMI), DisplayPort (DP), Peripheral Component Interconnect Express (PCIe), Thunderbolt (Thunderbolt), Converged Input Output (CIO) and any other high speed broadband wired communication Broadband wireline data communication systems such as the NXP require multiple processing stages within their electronic circuitry. [0003] The wideband data communication system circuitry may include several stages including modules for equalizing, amplifying and / or redriving the signal for each data channel. Often one stage doesn't provide enough gain or equalization. In ...
