中文摘要：

随着航天遥感载荷的日益复杂，CCD成像电路中相关双采样芯片（CDS）和通用A／D芯片构成的模数转换电路已不能满足要求。提出了基于集成相关双采样电路和A／D电路的单芯片（AD9814）CCD模数转换电路方案，用于星载光谱仪设备。介绍了该方案的芯片选择、软硬件设计和实验电路构建，并进行了相关实验，结果表明此光学系统的信噪比优于12bit，AD9814的抗辐照指标为15krad，所提出方案可用于航天工程。

英文摘要：

With the increasing complexity of remote sensing load, the analog/digital （A/D） conversion circuit composed of the correlated double sampling （CDS） chip and common A/D chip is unable to meet the requirements in CCD imaging circuit： A single chip （AD9814） CCD analog to digital conversion circuit is proposed based on the integrated CDS circuit and A/D circuit isproposed, which is used in satellite- borne spectrometer devices. The chip selection, hardware and software design and experimental circuit construction of the scheme are introduced, and the related experiment is carried out. Results show that the optical signal-to-noise ratio of the system is better than 12 bit, and the radiation resistant index of AD9814 is 15 krad. The proposed scheme can be applied to aerospace engineering.
