📋 论文概要

该论文提出了一种4通道10.3Gb/s收发器，采用自适应相位均衡器来补偿PCB信道引起的相位失真，支持4至41dB的信道损耗。解决了高速有线通信中信道相位失真导致的信号完整性下降问题。

💡 主要创新点

• 提出自适应相位均衡器，能够动态补偿信道相位失真，提升高损耗信道下的信号质量。
• 实现4通道并行收发，每通道速率10.3Gb/s，总带宽达41.2Gb/s，适用于高损耗PCB背板。
• 针对4-41dB宽范围信道损耗进行优化，通过均衡技术扩展传输距离。

Walker1 1 Fujitsu Laboratories of America, Sunnyvale, CA, Fujitsu Laboratories, Kawasaki, Japan 2 In multi-Gb/s wireline communications, equalizers are used to compensate for channel-induced signal distortion in order to stretch the maximum distance of transmission. Both amplitude and phase can be distorted in a channel. Amplitude distortion is a frequency-dependent attenuation due to skin effect and dielectric loss, causing inter-symbol-interference (ISI). A transmitter (TX) discrete-time pre-emphasis (PE) filter, a receiver (RX) continuous-time Linear Equalizer (LE), and an RX Decision-Feedback Equalizer (DFE) are generally used to cancel ISI. At 10Gb/s or higher data rate, equalizers for up to 33 to 39dB Nyquist loss and up to 20 to 25dB adapted loss range were reported [1–3]. On the other hand, how to compensate phase distortion is not clearly understood in
