| 摘 要： | 文章通过对双色红外焦平面结构、工作模式、各种信号输入级电路的研究,提出了顺序和同步工作的两种焦平面读出电路结构,输入级都是直接注入方式。短波( SW)和中波(MW)二个波段的光电流分别在各自的电容上积分,然后输出到后级电路,初步获得了电路的仿真结果。

| Abstract: | Detector structures,work modes and signal input circuits for dual band infrared focal plane array are re-seached. Two signal input stage of readout circuits for our dual band IRFPA are presentsed, and simulation on the cir-cuits is carried out. The input stages of both simultaneous SW /MW dual-band FPAs and sequence SW /MW dual-band FPAs are direct injection circuits. Photocurrents resulting from the detection of two spectral band are integrated in each capacitor, and the signals then are put to latter processing circuits. |
