| Abstract:As one of the future development trends, dual-band infrared focal plane detectors are being applied in an increasing number of scenarios. This article focuses on the design of a driving circuit for the middle and long wave dual-band infrared focal plane detector, and proposes design methods for dual-mode driving circuit, independent dynamic range adjustment circuit, small analog signal conditioning circuit, dual-substrate switching circuit, power driving circuit, and distributed integration. This driving circuit can effectively transform the analog signal output from the sensitive element of the infrared focal plane detector, while providing the required bias voltage and driving timing for the infrared focal plane detector. The driving circuit of the middle and long wave dual-band infrared focal plane detector designed in this article achieves good imaging results after the fusion of middle wave and long wave images. |
