基于FPGA的数据采集系统中20MHz模拟通道设计

The design based on FPGA of 20MHz analog channels in the data acquisition system

数据采集系统就是为了完成数据采集过程,由为了完成某些特定信号或一组信号而由一系列软件和硬件组成的软硬件系统。模拟通道作为数据采集系统中的关键部分组成部分之一,其性能指标直接制约了数据采集系统的发展,如何使模拟通道具有更高的带宽,更好的交直流性能,更低的噪声,成为了数据采集系统中模拟通道设计研究的主要内容和关键内容。

Data acquisition system is to complete the data collection process,from order to complete some specific signal,or a group of signals consists of a series of software and hardware components of the software and hardware systems.Analog channel data acquisition system as a key component of some of its performance constraints for the development of data acquisition system,how is the analog channels with higher bandwidth,better AC and DC performance,lower noise,as the data acquisition system design of analog channels the main content and key content.
