| Abstract: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. |
