摘要
通过外部电路提高Ａ／Ｄ转换的分辨率，必须和提高Ａ／Ｄ转换的精度同步，否则，提高分辨率的意义就非常有限。外部电路不仅会引入误差，还会引起振荡。本文分析了外部电路应具有的精度指标。
The improvement of A/D converting resoluatlon must be together with its conversion accuracy,or thus work will be of less meaningful.However,by this way,some error will be brought in and vibration caused.This paper analyzes its accuracy index the external circuit should possess;and gives a simple method by which no vibration will be occured.
