基于可编程芯片的信号调理电路设计

摘要

This paper describes the signal conditioning circuit in data acquisition and control systems, and pre- sents the signal conditioning circuit design program based on analog programmable devices. PAC-Designer software through the conditioning circuit programming, and then downloaded to chip ispPAC20, to achieve amplification, summation, filtering, circuit requires fewer external components, and the performance of the circuit is fine.%本文介绍了信号调理电路在数据采集和控制系统中的作用,并提出了基于模拟可编程器件的信号调理电路设计的方案。通过PAC-Designer软件进行调理电路的编程,下载到ispPAC20芯片,实现放大、求和、滤波等功能。电路外接器件少,且电路性能优良。
