【摘要】 提出了一种快速以太网卡芯片数模混合自适应均衡器的体系结构。该结构采用Sign SignLMS算法 ,可有效地补偿双绞线传输的损耗 ,消除向前码间干扰 ;由于采用数模混合电路结构 ,无需高速A/D转换器和数字乘法器 ,降低了功耗和缩小了芯片面积。该自适应均衡器已经过TSMC 0 35 μM 1P5MCMOS工艺验证。更多还原

【Abstract】 This thesis presents an adaptive equalizer architecture in fast ethernet NIC integrated circuit. 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.更多还原
