摘要
数字化红外焦平面探测技术作为第三代红外焦平面技术成为近年来被研究的热点。本文提出了一种将像素级数字化技术与TDI技术相结合的红外焦平面读出电路,使得电路实现大动态范围的同时满足低功耗设计。文中在0.18μm CMOS工艺模型下,对电路进行设计仿真,该读出电路电荷处理能力可达到5.04 Ge-,动态范围最高达到101.5 dB,在典型长波积分电流应用下电路功耗仅95.8 mW。
As the third-generation infrared focal plane technology,digital infrared focal plane detection has been studied widely in recent years.An infrared focal plane readout circuit that combines pixel-level digitization technology with TDI technology is proposed in the paper.The readout circuit can achieve a large dynamic range and low-power.The circuit is designed and simulated with 0.18μm CMOS process model in this paper.The charge processing capacity of the readout circuit can reach 5.04 Ge-,the dynamic range is up to 101.5 dB,and the power consumption is only 95.8 mW working under long-wave integrated current application.
