摘要：
Digital readout of infrared focal plane array (IRFPA) orients its development. Compared with traditional analog IRFPA, digital IRFPA has many advantages. The critical technique of digital IRFPA is the digital readout integrated circuit (DROIC). The design and implementation of the 1280 × 1024, 10 μm DROIC was introduced in detail in this paper. The DROIC was tested and the results showed its noise was 157 μV, the power consumption was 165 mW when frame rate was 50 Hz, and the column fix pattern noise was 0.1%. The DROIC interconnected short-wave infrared detector through flip chip successfully and completed imaging. The images had good resolution and rich details. The test results and images' effect indicated that the DROIC has some features, such as low noise, wide transmission bandwidth and good resistance to interference and so on, and contributes to the development of IRFPA's performance.
