Abstract
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.
