摘要：本文研究了一種新型的硅光電探測器（即智能探測器），它使用CMOS兼容工藝，將光電二極管陣列與信號的放大、處理電路及輸出電路集成在一個芯片上，在輸入光信號的同時在輸出端即可得到串行的電信號。該芯片具有噪聲低，速度快，用途廣泛等特點(diǎn)。對芯片的測試結(jié)果表明，智能探測器的電路設(shè)計和工藝設(shè)計均取得初步成功，基本達(dá)到預(yù)期的設(shè)計目標(biāo)。

Study on Integrated Smart Photo-detector SOC
Abstract: A novel integrated CMOS smart sensor which is intended to provide flexible low noise amplification and multiplexing component is presented in this paper. Low level current output devices, such as a photodiode array, can be directly connected to its input. It has 64 channels, and each channel has a photo-sensitive preamplifier and the ability to provide double correlated sampling and hold. This chip may also be used as general-purposed multi-input multiplexer for medical, scientific, or industrial instrument applications. There are no similar products reported in China yet. The test results show that the expected functions of the chip can be fulfilled.
