微弱电流信号测量方法的研究论述
Research and Discussion on Measuring Method of Weak Current Signal
摘要: 生产实践、科学研究中存在着大量的微弱电流信号，对于高精密仪器而言，微弱电流信号的准确测量关系着仪器的正常使用情况。但因其值微弱，易受干扰影响，微弱电流的测量一直是人们在探讨和关注的焦点。本文介绍了目前微弱电流测量的发展现状和两种常用基本测量方法I-V变换法和I-F变换法的原理及其对比分析，并给出了两种测量方法在使用过程中提高测量性能的措施方法。
Abstract: There are a large number of weak current signals in production practice and scientific research. For high-precision instruments, the accurate measurement of weak current signals is related to the normal use of the instrument. Because of its weak value and susceptibility to interference, the measurement of weak current has always been the focus of discussion and attention. This article introduces the current development status of weak current measurement and the principles and comparative analysis of the two common basic measurement methods current-to-voltage conversion method and current-to-frequency conversion method, and provides measures to improve measurement performance during the use of the two measurement methods.
