摘要

用于中央局的双极ADSL线路驱动器的MTPR达到75dB。采用单主动终端拓扑，总功耗为710mW，其中输送到线路的功率为20.4dBm。ab类偏置使得4mA静态电流不受工艺、温度和电源变化的影响。

740mW ADSL line driver for central office with 75dB MTPR

A bipolar ADSL line driver for central office achieves 75dB MTPR. Employing a single-active-termination topology, it has 710mW total dissipation including 20.4dBm delivered to the line. Class-AB biasing makes the 4mA quiescent current independent of process, temperature, and supply variations.
