A 100 MHz 50 /spl Omega/-45 dB distortion 3.3 V CMOS line-driver for Ethernet and fast Ethernet networking applications

摘要

A fast line-driver for networking applications is intended to drive cables with large, low-distortion sine-waves for 10BASE-T and sharp-edged pulses for 10BASE-T type data communications. The driver uses current-feedback architecture for small-signal and large-signal closed-loop bandwidths <100MHz. Unlike previous current-feedback opamps, it has a fully differential architecture.
