一款低成本硅PIN光电二极管偏置电路的设计及应用
资料介绍
硅PIN光电二极管在微弱光信号检测领域的应用越来越广泛，但其效果会受到偏置电压等因素的影响，稳定性高、纹波系数小的偏置电压对准确获得被测信号来说是必不可少的。设计一款基于TPS61040电压转换芯片的硅PIN光电二极管偏置电路，并将其用于NaI（Tl）晶体的微弱光信号检测，取得了良好的效果。
The Si-PIN photodiodes have been more and more widely used in the areas of weak light signal detection,but the result of detection is more likely affected by bias voltage and other factors. The high-stability bias voltage with low ripple co-efficient is essential for accurately achieving the detected weak light singal. A Si-PIN photodiode bias circuit based on TPS61040 DC/DC boost converting chip was design and applied to the weak light signal detection of the NaT（Tl）scintillator. A good re-sult was achieved.
