【 摘 要 】

To ensure the whole system work properly, analysis and design of intelligent sensor signal measurement circuit is completely necessary. In this study, we design a typical I/V conversion circuit by modeling analysis of measuring system which consists of a photodiode and a multi-channel data multiplexer, and then analyze and simulate it. It is found that the stability problem exist in the typical I/V conversion circuit. In order to meet the requirement of A/D conversion, some measurement is taken to solve this problem, which ensures the whole system run smoothly.
