摘要
提出了一种快速以太网卡芯片自适应均衡器的体系结构 .该结构采用 Sign- Sign L MS算法 ,有效地补偿双绞线传输的损耗 ,消除向前码间干扰 ;具体实现采用数模混合电路 ,无须高速 A/ D转换器和数字乘法器 ,大大降低功耗和芯片面积 .该自适应均衡器已经过 TSMC0 .35 um1P5 M CMOS工艺验证 ,工作电压为 3.
This thesis presents a adaptive equalizer architecture for fast Ethernet applications. Sign-Sign LMS algorithm is adopted to efficiently compensates the twisted pair loss and cancel Intersymbol Interface. Mixed-signal implementation eliminates the need for 125Mb/s A/D converters and digital multipliers, which reduce the power and chip area. The adaptive equalizer has been verified by TSMC CMOS 0.35 1P5M process, VDD voltage is 3.3V.
