TECHNICAL ABSTRACT (Limit 2000 characters, approximately 200 words)
We propose to investigate the feasibility of developing a low noise, two-side buttable, 64x64 readout multiplexer with the following key design features:
1- By far the largest readout array developed for far IR detectors to date. Four of these readout can be butted together to form a >16k-pixel mosaic array satisfying the need of the next generation of astronomical instruments.
2- Optimized for use with far infrared detectors requiring low bias levels. The unit-cell design will maintain constant bias across the detector during the integration eliminating non-linearity and detector debiasing. The design will also minimize the pixel-to-pixel DC variation which improves the bias uniformity across all pixels of the array.
3- Capable of operation at cryogenic temperatures at least as low as 1.6K. Advanced monolithic cryo-CMOS technology will guarantee deep cryogenic operation with minimal impact on noise performance.
4- Offers the potential of being directly hybridized to IR detector arrays using indium-bump technology.
This technology has been identified by NASA as well as the science and astronomy community as key for future far IR astronomy. It fits well within the scope of the SBIR Subtopic S1.04 and will be a benefit to many large and small NASA missions including SAFIR/CALISTO and SOFIA.

POTENTIAL NASA COMMERCIAL APPLICATIONS (Limit 1500 characters, approximately 150 words)
Astronomical instruments developed under Program such as SAFIR/CALISTO, science instruments for SOFIA, upcoming projects under Astrobiology Program, balloon-borne instruments for atmospheric research, and laboratory science instruments.

POTENTIAL NON-NASA COMMERCIAL APPLICATIONS (Limit 1500 characters, approximately 150 words)
Aerospace industry: In addition to the aerospace companies that are under contract to NASA and directly participate in the space program, there are those that independently manufacture infrared detector arrays in large formats. Some aerospace companies that would be interested in our product are Raytheon Vision Systems, Boeing, Rockwell, and Ball Aerospace. Science groups at universities and national labs: Astronomical science instruments for observations at ground-based observatories and instruments for basic research.

NASA's technology taxonomy has been developed by the SBIR-STTR program to disseminate awareness of proposed and awarded R/R&D in the agency. It is a listing of over 100 technologies, sorted into broad categories, of interest to NASA.
