A 6-Gbs MIMO Crosstalk Cancellation Scheme for High-Speed IOs
提出了一种2-6 Gb/s连续时间MIMO串扰消除架构，显著提升信号完整性。
0.03 mm², 2.8 mW/Gbps/lane
MIMO串扰消除高速IO信号完整性低功耗
▸创新点1：连续时间MIMO串扰消除架构 - 该方法创新性地采用连续时间多输入多输出（MIMO）架构，有效消除了高速IO中的串扰问题，在2-6 Gb/s的数据速率下显著提升了信号完整性，测量结果显示眼图的水平和垂直开口分别改善了67%和58.2%。
▸创新点2：串扰能量再利用技术 - 该电路创新通过重新利用串扰能量，不仅减少了信号损失，还在严重串扰环境中保持了高信号完整性，特别是在串扰完全关闭数据眼的情况下仍能有效工作。
▸创新点3：低功耗设计 - 该设计在系统层面实现了显著的功耗优化，MIMO-XTC部分仅消耗2.8 mW/Gbps/lane，比之前提出的XTC方案降低了50%，同时芯片面积仅为0.03 mm²，展现了高效的能效比。
▸创新点4：高性能指标验证 - 通过在各种FR4通道间距和数据速率下的实测验证，该方案在眼图改善和功耗方面均达到了目前已知的最佳性能，为高速IO设计提供了可靠的参考标准。
Abstract
A continuous-time multiple -input multiple-output
crosstalk cancellation (MIMO-XTC) architecture operating at 2–6
Gb/s has been proposed. The performance of the XTC equalizer
has been measured with various spacings of FR4 channels and data
rates. The crosstalk energy reutilization technique ef ficiently han-
dles crosstalk and achieves high si gnal integrity in severe crosstalk
environments where crosstalk had completely closed the data eye.
Measurement results show improvement in
