Abstract :
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.
