基于新型专用运放的现代传感器调理电路设计

摘要

越来越多地选用新型专用运放设计现代传感器调理电路，将成为必然趋势。结合现代传感器调理电路设计中的若干重要技术问题，重点讨论了全差分运放、带EMI/RFI滤波器的仪表放大器、带远程负载检测的仪表放大器、单电源微功耗仪表放大器、静电计级运放等新型专用运放，在现代传感器调理电路设计中的具体应用。表明选用合适新型专用运放设计现代传感器调理电路，可以解决选用常用运放难以解决的问题或得到更高的性能。相关的设计思想与设计技术，也适用于其他类似应用实践。%It's becoming more and more popular to design modern sensor signal conditioning circuits with proper newer specialty op amps.On the purpose of practices,designing practical modern sensor signal conditioning circuits with several newer types of specialty op amps is studied.The conclusions il ustrated that newer specialty op amps can offer some important benefits compared to universal op amps for a number of sensor applications.The ideas and techniques discussed can be used to solve similar problems.
