摘　　要：分析了高光谱应用下的一种1024×256短波红外探测器组件读出电路设计。针对高光谱弱信号红外探测应用,该电路采用CTIA像元结构,达到72%的量子效率,并有效抑制了复位结构带来的漏电效应,使线性度和输出摆幅得到显著的提高。并通过列级和输出级的优化设计,得到了良好的噪声性能。This paper recomnmnds a read-out circuit for 1024 × 256 hyperspectral SWIR FPA. For application of weak signals hyperspeetral infrared detection,the circuit adopts the CTIA structure. The system has 72% of quantum effi-ciency,and effectively restrain the leakage effect caused by reset structure. The linearity and output range is signifi-cantly improved. And through optimized design of column circuit and output structure, good noise performance is ob-tained .
