面阵CCD辐射敏感参数测试电路设计及试验验证
Test Circuit Design and Radiation Experiment Verification of Array CCDs
摘要
Abstract
The ICX285AL array charge coupled devices(CCDs)which are widely used in aerospace,scientific research,industrial applications,consumer electronics,and other fields are studied.A test circuit for testing the radiation sensitive parameters of array CCDs with field programmable gate array(FPGA)as the control core is designed.The test circuit mainly includes the FPGA control module,the CCD drive module,the analog-to-digital(A/D)correlated double sampling module,the data transmission module,and the power module.In terms of the hardware circuit design,the functional division of test circuit and the core chip selection of each module are carried out,the schematic diagram of test circuit is designed,and the layout and wiring of PCB board are optimized.Regarding the test circuit driver design,the FPGA driver is developed by Verilog HDL hardware description language,and the functions of image data acquisition,signal processing and conversion,data transmission and communication are realized by the FPGA timing control pulse.In this test circuit,the analog signal and the digital signal are separated to avoid the influence of the high-frequency digital signal on the high-precision analog signal.The typical characteristics of the CCD performance degradation induced by proton radiation are tested,and the reliability of the test circuit and its applicability to radiation effect test are verified.The research will provide the test technical support for the CCD radiation experiment research.关键词
