Low Noise Infrared Detector Readout Array for 2 Kelvin

Abstract:

Space based low background infrared measurements present stringent performance requirements
on the infrared detector arrays and their associated readout multiplexer circuitry.
Very low temperature cryogenics environments (2 Kelvin) are required by these systems
to achieve detector performance levels. These cryogenics environments pose technical
challenges ont he readout multiplexer performance. Although significant performance
improvements have been realized in low noise low temperature readout multiplexers,
substantial systems penalties must be paid in the use of elevated temperature stages
to operate these devices. This proposed effort will demonstrate that low noise infrared
detector array readout multiplexers can be achieved through the use of TRW's advanced
cryogenic-Complementary Metal Oxide Semiconductor (cryo-CMOS) fabrication process.
Low background infrared systems such as those on the space infrared telescope facility.
