Radiation-hardened Reconfigurable Digital Dual-band Infrared ROIC

A 1280 x 1024, 12-micron-pitch format radiation-hardened dual-band digital infrared readout integrated circuit (ROIC) will be developed. The features of the reconfigurable adaptive detector integrated circuit (RadIC) include: low-noise in-pixel amplifiers, in-pixel analog-to-digital conversion (ADC), extended > 22-bit dynamic range with temporal-photon flux-rate encoding, high-rate readout, and asynchronous transient threat detection capability. In Phase I, the key pixel, end-of-column, and detector array circuits will be designed and their performance simulated. Then, after a preliminary design review (PDR), key circuits and small-sized arrays will be laid out and their properties will be extracted. Next, the design will be validated and taped out for fabrication. In Phase II, a fully-functional ROIC will be fabricated, integrated with a detector array in an integrated dewar cooler assembly (IDCA) and tested with camera electronics.
