Abstract
Goodrich, SUI has developed a 15 μm pitch, 1280 x 1024 pixel InGaAs focal plane array (FPA) with low noise, and visible to near infrared (0.4 μm to 1.7 μm) wavelength response for day and night vision applications. The readout integrated circuit (ROIC), which uses a capacitive transimpedance amplifier (CTIA) pixel, is designed to achieve a noise level of less than 50 electrons, due to its small integration capacitor. The ROIC can be read out at 120 frames per second, and has a dynamic range of 3000:1 using rolling, non-snapshot integration. The ROIC was fabricated in a standard CMOS foundry process, and was bump-bonded to Vis-InGaAsTM detector arrays. SUI has successfully hybridized 15 μm pitch 1280 x 1024 pixel FPAs, and produced imagery.
