为了验证被设计出的 A/D 变换器(ADC)的速度和精度是否达到预定要求,分析理论与实际产生差距的原因,必须借助于一些比较严格的科学的测试方法,方法不正确显然不能说明结果正确与否。目前具体的测试方法很多,这里仅以0.3μs 七位串并行ADC 为例,将我们所采用的几种测试方法介绍如下。一、静态精度测试静态测试是精确测定 ADC 基本工作状态正常与否的必要手段。没有静态的正常工 In order to verify whether the speed and accuracy of the designed A / D converter (ADC) meet the predetermined requirements and to analyze the causes of the discrepancy between theory and practice, we must rely on some of the more rigorous and scientific test methods. The result is correct or not. At present, many specific test methods, here only 0.3μs seven-bit serial ADC, for example, we will use several test methods are described below. First, the static accuracy test Static testing is an accurate measure of the basic work of ADC normal or not necessary means. No static normal work
