提出一种用于10和28 Gbps直接调制激光器的电子色散补偿收发器，通过线性均衡器和双采样决策反馈均衡器改善色散问题。
40nm CMOS, 0.9V, 28 Gb/s
电子色散补偿直接调制激光器啁啾效应决策反馈均衡器光纤传输
▸创新点1：线性均衡器与双采样决策反馈均衡器（DFE）结合，通过线性均衡器预处理信号后，双采样DFE进一步消除码间干扰，显著提升接收灵敏度（28 Gb/s下提升1.3 dB，10 Gb/s下提升7 dB），属于接收机电路创新。
▸创新点2：模式依赖脉冲整形滤波器在发射端动态调整脉冲形状，针对不同数据模式补偿啁啾引起的色散，解决了传统均衡方法对时变色散无效的问题，属于发射机算法与电路协同创新。
▸创新点3：针对瞬态啁啾（28 Gb/s短距）和绝热啁啾（10 Gb/s长距）分别优化补偿策略，通过自适应参数配置实现跨速率（10/28 Gb/s）和跨距离（3 km/105 km）的通用性，属于系统级架构创新。
▸创新点4：采用40nm CMOS工艺集成双通道收发器与全局时钟发生器，单通道功耗仅105.5 mW@0.9V，面积效率达2.8mm²/双通道，体现高集成度低功耗设计创新。
Abstract
This paper presents an electronic dispersion com-
pensation (EDC) transceiver to encompass extended reach
of both 10- and 28-Gb/s directly modulated lasers (DMLs).
In DML-based links, direct modulation of laser diodes induces
power-dependent frequency chirp on the generated optical sig-
nals, which causes severe chromatic dispersion as well as pattern
dependence on the received signal after optical fiber transmission.
Such time-varying nature of the dispersion makes conventional
equalization meth
