摘要
该文论述了光电检测电路设计的基本方法,由于在光电检测电路中会出现噪声的干扰,因此文章重点分析了光电检测电路中的噪声,并对噪声进行了简单的计算,通过对噪声的分析和计算,提出了一些降低噪声的措施,如选用低噪声的元器件,选择合适的晶体管放大器的直流工作点等。
This paper discusses the basic design of photoelectric detection circuit of photoelectric detection methods,because in the circuit will appear the noise,so the article analyzed the noise of the circuit of photoelectric detection,through the analysis of the noise,and puts forward some measures to reduce the noise,if choose low noise components,select the appropriate transistor amplifiers dc robustly,etc.
