空间天文学要求大面积低温红外焦平面阵列（FPA）具有高量子效率、极低暗电流、低功耗和背景噪声性能。为了满足这些要求，特别是在5-15 K的温度下，圣巴巴拉研究中心设计并制造了一种新的多路复用器CRC-744。罗切斯特大学对将InSb探测器阵列与CRC-744多路复用器结合制成的FPA进行了评估。最好的阵列在15 K下实现了5 e −（12 s积分）和7 e −（200 s积分）的读取噪声，Fowler-64采样，15和29 K下的平均暗电流<0.2 e−/ s，15和29 K下的平均量子效率为87%。10%-90%上升时间为4 μs，驱动600 pF外部负载。当全速运行（100%占空比）时，功耗为0.3-0.4 mW。满阱容量为105 e−（230 mV），外加偏压为400 mV。上述测试结果表明，FPA满足本底空间限制的要求。
Space astronomy requires large-area cryogenic infrared focal plane arrays (FPAs) with high quantum efficiency, extremely low dark current, low power dissipation, and background limited noise performance. To meet these requirements, especially at temperatures of 5–15 K, Santa Barbara Research Center designed and fabricated a new multiplexer, CRC-744. The FPAs made by bonding InSb detector arrays to CRC-744 multiplexers were evaluated at the University of Rochester. The best array achieved the read noise of 5 e − with 12 s integration and 7 e − with 200 s integration with Fowler-64 sampling at 15 K, the average dark current of <0.2 e−/ s at both 15 and 29 K, and the average quantum efficiency of 87% at both 15 and 29 K. The 10%–90% rise time was 4 μs driving a 600 pF external load. The power dissipation was 0.3–0.4 mW when running flat-out (100% duty cycle). The full well capacity was 105 e− (230 mV) with 400 mV of applied bias. The above test results demonstrate that the FPAs meet background-limited space ...
