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 ON THE READOUT MULTIPLEXER PERFORMANCE. ALTHOUGHSIGNIFICANT 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 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.
