近年来,随着科学技术的发展,尤其是数字技术、大规模集成电路及微处理器的迅速发展,出现了许多新型数率化智能仪器,如波形分析系统(亦称信号处理系统)、波形存贮器、数字存贮示波器、数据采集系统及过程控制系统等.它们都大量地应用了模拟信号的数字处理技术,而其中的关键部件是快速模-数转换器.目前已研制生产出各种类型的快速模-数转换器.本文介绍几种用于波形存贮器中的快速模-数转换器的工作原理及实际应用电路.
In recent years, with the rapid development of science and technology, especially digital technology, large-scale integrated circuits and microprocessors, many new types of digitized smart instruments have emerged, such as waveform analysis system (also referred to as signal processing system), waveform Memory, digital storage oscilloscopes, data acquisition systems and process control systems, etc. They all use a large number of digital signal processing techniques, and the key component is a fast analog-digital converter. Has been developed to produce Type of fast analog-to-digital converter.This article describes several working principles and practical circuits for fast analog-to-digital converters used in waveform memory.
