摘要
光电探测器前置放大电路设计的好坏直接影响到整个系统的探测精度.介绍了光电探测器前置放大电路的设计与研究,主要阐述了光电转换电路、放大电路带宽、放大电路噪声、放大电路稳定性以及其他一些需要注意的问题,并设计了一种能够有效降低噪声和温飘,具有大的动态输入范围的放大电路.
The design of the pre-amplifier circuit of photoelectric detector systems can directly affect the de- tecting precision of the whole systems. The design of pre-amplifier circuit from a photoelectric detector was in- troduced. The photoelectric conversion circuit, amplifier circuit bandwidth, amplifier circuit noise, amplifier circuit stabilization and other questions were mainly discussed, and an amplifier circuit capable of effectively decreas- ing the noise, the temperature drift and with a large dynamic range was designed.
