摘　　要：双波段红外焦平面探测器是未来发展趋势之一,在越来越多的场景中得到应用。针对中长波双波段红外焦平面探测器的驱动电路进行设计,提出了包括双模式驱动电路、独立动态范围调整电路、低模拟信号调理电路、双衬底切换电路、电源驱动电路和分布式积分的设计方法。该驱动电路能够对红外焦平面探测器敏感元输出的模拟信号进行有效变换,同时给红外焦平面探测器提供所需的偏置电压和驱动时序。本文所设计的中长波双波段红外焦平面探测器驱动电路在中波和长波图像融合后具有良好的成像效果。Dual-band infrared focal plane detectors are one of the future development trends and are being used in more and more scenarios.Aiming at the design of the driving circuit for the mid-and long-wave dual-band infrared focal plane detector,the design method proposed includes a dual-mode driving circuit,an independent dynamic range adjustment circuit,a low analog signal conditioning circuit,a dual-substrate switching circuit,a power driving circuit and distributed integration.The driving circuit can effectively transform the analog signal output by the sensitive element of the infrared focal plane detector,and provide the required bias voltage and driving timing to the infrared focal plane detector.The driving circuit of the mid-and long-wave dual-band infrared focal plane detector designed in this paper has a good imaging effect after the mid-wave and long-wave images are fused.
