Abstract

We have developed a novel readout circuit architecture realizing a TEC-less (Thermo-Electric Cooler) operation for an SOI diode uncooled infrared focal plane array (IRFPA). Through the fabrication of an SOI diode uncooled 320 x 240 IRFPA adopting the readout circuit architecture with our existing 25μm pixel-pitch technology, we demonstrate that the variation of the output DC level of the pixels is successfully suppressed in environmental temperatures from -10°C to 50°C. The developed TEC-less technology greatly enhances the ability of the SOI diode uncooled IRFPA, which inherently possesses excellent uniformity and low noise features.
