摘要:

科学级CCD驱动时序对CCD可靠、稳定的运行起着重要作用。针对e2v公司的CCD47-20 BI AIMO(advanced inverted mode operation)提出了一种基于FPGA(field programmable gate array)的科学级CCD驱动时序的设计方案。该设计方案以Actel公司的FPGA-APA600为硬件设计平台,在LiberoIDE v9.0开发环境中,使用Verilog语言对驱动时序进行硬件描述,并采用第三方软件ModelSim6.0进行功能仿真。配合Matrox公司的图像采集卡进行图像采集实验,实验结果表明,CCD能正常、稳定地工作,所设计的驱动时序满足CCD47-20 BI AIMO的时序要求。目前,该设计已应用于氧气探测空间外差干涉仪的CCD读出电路,满足工作要求。

Abstract:

Design of driving schedule is important for CCD to perform well. A driving schedule design based on FPGA (field programmable gate array) is put forward for the scientific grade CCD47-20 BI AIMO (advanced inverted mode operation) of e2v Company. This design is developed on the FPGA-APA600 hardware platform using Verilog language in LiberoIDE v9.0 development environment, and simulated in ModelSim6.0. Image acquisition experiments were implemented with the image collection card of Matrox Company. The experiment indicated that the CCD performed stably, and the design met the driving requirements of CCD47-20 BI AIMO. The result has been applied to CCD readout circuit of spatial heterodyne interferometer for oxygen detection and performs well.
