基于光电传感器的脉搏信号采集电路优化设计
The Optimization Design on Acquisition Circuit of the Pulse Signal Based on the Photoelectric Sensor
摘要
Abstract
By briefly introducing the characteristics of pulse signal and the working principle of the photoelectric sensor with OPT101 as its core,this paper has designed and optimized a conditioning circuit which can amplify the filtering of pulse signal based on high common mode rejection ratio of differential circuit. Experiments show that the optimized circuit can capture the pulse waveforms required by the A/D conversional input voltage clearly. For this optimized circuit,low cost and simple and reasonable structure are its important advantages.关键词
