摘要
介绍了一种用于ＨＤＳＬ高比特数字用户环路系统的新的模拟前端电路（ＡＦＥ——ＡｎａｌｏｇＦｒｏｎｔＥｎｄ），这种电路具有低功耗，低成本，体积小，性能优良等特点，文中就电路的组成，各子电路的基本构造及性能等进行了叙述，最后给出了这种新电路与过去所用同类电路的一些性能比较结果。
This paper introduces a new optimized AFE(Analog Front End) circuit used in the HDSL system which has several advantages such as low power consumption,low cost,reduced size and better performance,describes the construct of this circuit and the basic components and properties of its subcircuitss,and compares the original AFE with the new AFE.
