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 and vertical opening of the eye diagram by 67% UI and 58.2%, respectively, which is the best known improvement to date. The MIMO-XTC portion occupies 0.03 mm and consumes 2.8 mW/Gbps/lane, which is two times lower than prev iously proposed XTC schemes.
