基于光电传感器的脉搏信号采集电路优化设计
资料介绍
简要介绍了脉搏信号的特点以及以OPT101芯片为核心的光电传感器的工作原理。设计了一个对脉搏信号进行滤波放大的调理电路并进一步对其优化，优化电路利用差分电路的高共模抑制比的特点，实现对脉搏信号的滤波放大处理。经实验测试表明，采用优化后的电路能够在示波器上采集到符合A/D转换输入电压要求的清晰脉搏波波形。此电路具有成本低、结构简单合理等优点。
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.
