压控振荡器和计数器组成A／D转换的设计与实现

Design and Implementation of A/D Conversion Using a Controlled Oscillatory and Data Counters

首先介绍Ａ／Ｄ转换芯片的原理，然后阐述压控振荡器（Ｖ－ｆ）和计数民组成模数（Ａ／Ｄ）转换的原理。利用该原理实现了１０位高速Ａ／Ｄ转换的功能，并设计出实用的Ａ／Ｄ转换电路。最后测试了利周该方法实现Ａ／Ｄ转换的性能，给出其检测结果。同时说明利用此原理实现不同位数和转换速度的Ａ／Ｄ转换器的方法。

The paper introduces the principle of A / D conversion chip, and then describes the A/ D conversion mechanism based on a controlled oscillatory and data counters. With that mechanism, a 10-bit high-speed A/ D convertor is implemented.However, as explained in the paper, the mechanism can be used to realal A / D conversion of different bits and speeds. Finally, some results of peiformance tests are given.
