A 90nm CMOS DSP MLSD Transceiver with Integrated AFE for Electronic Dispersion Compensation of Multi-mode Optical Fibers at 10Gb/s

📋 论文概要

该论文介绍了一款采用90nm CMOS工艺的DSP MLSD收发器，集成了模拟前端（AFE），用于多模光纤的电子色散补偿（EDC）。该收发器通过最大似然序列检测（MLSD）实现均衡，解决了多模光纤链路中色散导致的信号失真问题，支持10GBASE-LRM标准。

💡 主要创新点

• 首次在90nm CMOS中集成模拟前端与DSP MLSD收发器，实现多模光纤的电子色散补偿。
• 采用最大似然序列检测（MLSD）算法替代传统均衡器，提高了色散补偿性能。
• 高集成度设计降低了系统功耗和面积，适用于长距离多模光纤链路。

Widespread use of electronic dispersion compensation (EDC) for MMF is prompted by the ratification of the 10GBASE-LRM standard [1]. A number of studies have demonstrated the superiority of MLSD for this application (see
