摘要
针对现有的锑化铟—铟磁阻式传感器的灵敏度、噪声等电学特性的测量过程所存在的不足之处,本文提出一种改进的测量方法,并且在此基础之上设计了一个自动测试仪,采用ADS744型A/D转换器和CH365型专用PCI接口芯片,达到高的采样速率与传输速率,实现对此种传感器的电学特性的快捷、精确的测量。
A new way to measure the electronic character of InSb-In magnetoresistive Sensor including sensitivity and noise is presented. It can solve the problems which exist in the traditional measuring way. Basing on the new way, an auto measuring system is designed to measure the electronic character quickly and accurately.
