摘要

为了满足双频红外探测的需求，本文提出了一种中短波双色红外焦平面读出电路的设计方案。主要设计了双色像素单元电路和工作模式切换电路，最后设计了面积为12.5 × 12.5mm2的双色红外焦平面读出电路芯片。测试结果表明，本文设计的芯片实现了双色读出功能，获得了良好的成像效果，输出摆幅范围为1.55~4.7V，输出帧频可达到60Hz，最大功耗小于200mW，动态范围约为79.8dB。

Design of 320×256-30um DI Medium and Short Wave Two-color IRFPA Readout Circuit

In order to meet the demand of dual-band infrared detection, this paper presents a design scheme of medium and short wave two-color infrared focal plane readout circuit. The two-color pixel unit circuit and operating mode switching circuit are mainly designed, and finally designed two-color infrared focal plane readout circuit chip with area 12.5 × 12.5mm2. The test results show that the chip designed in this paper realizes the function of two-color readout and obtains good imaging effect The output swing range is 1.55~4.7V, the output frame frequency can reach 60Hz, the maximum power consumption is less than 200mW, and the dynamic range is about 79.8dB.
