高速高精度ADC系统分析

Analysis of High Speed ADC System

对于提高模数转换系统的速度和}生能，并使用相对低速的电路来实现高速采样的模数转换系统来说，时间交叉采样模数转换系统是一种非常有效的方法。本文介绍了时间交叉采样法的基本原理和实现方法，并对系统中各通道间的失配对整个系统性能的影响做出了分析，给出了仿真图形。

Time-interleaving sample technique that can improve the speed and performance of ADC system is a very effective method on the application of using relatively low speed circuits to realize high speed and high performance ADC systems. The basic principles and implementation methods of time-interleaving sample are introduced in this paper. The mismatching on the performances of time-interleaving ADC systems are analyzed. The emulate figures are obtained in this paper.
