摘要

本文将报道一种模拟CMOS三芯片组，它与相关联的调制解调器数字信号处理器接口。该芯片组可对速率为2400b/s的分带调制解调器和速率为16800b /s的回波消除调制解调器进行A/D和D/A转换、复制回波信号的模拟相减、滤波、自动增益控制和模拟载波检测。在4μ CMOS中实现。

A full duplex analog front-end chip set for split-band and echo-canceling modems

This paper will report on an analog CMOS three-chip set which interfaces to an associated modem digital-signal processor. The chip set performs A/D and D/A conversion, analog subtraction of replicated echo signal, filtering, automatic gain control, and analog carrier detection for split-band modems up to 2400b/s and echo-canceling modems up to 16,800b/s. Implementation was in 4μ CMOS.
