AbstractMissile Defense Agency (MDA) requires high performance, high sensitivity and low noise infrared sensors for space based sensing applications that operate in environments where radiation hardness is essential to mission operation. Radiation hard by design (RHBD) readout integrated circuits (ROICs) decrease the overall cost of focal plane arrays (FPAs) by exploiting existing commercial foundries rather than relying on increasingly scarce and costly "proven" foundries that offer radiation hard by process (RHBP). Commercial CMOS fabricated with thick silicon-on-insulator (SOI) wafers will provide exceptional radiation performance to total dose (> 300kRads (Si) with both ionizing and nuclear particles) and mitigate single-event upsets and latch-up. The RHBD concept utilizes enclosed gate NFET layout and adaptive bias to optimize circuit performance for infrared FPAs operating at cryogenic temperatures.
