Design and implementation of mixed-signal adaptive equalizer in fast ethernet NIC integrated circuit
Zhu Quanqing · Systems engineering and electronics · 2004
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.
