KARI designed On-Board Computer for Korean LEO Satellites using new architecture and technologies. This paper introduces the detail design, implementation of OBC and environment test results at FM OBC Unit.
A 1.4 μm-pitch pixel of CMOS image sensor, which is the smallest to date, has been successfully developed and integrated into 8M density for the first time. To overcome the crucial degradation of the saturation charge and sensitivity, a novel photodiode structure extended under transfer gate and an elaborate optical design including very thin tungsten pixel routing with 65 nm-grade design rules are...
The properties of sub-micrometer scaled MTJs using various synthetic antiferromagnetic (SAF) free layer were studied using remanent-state measurement. The magnetic tunnel junction device was a structure consisted of TiN/PtMn/CoFe/Ru/CoFe/AlO/NiFe/Ru/NiFe/Ta. It was found that junctions using single free layer showed complex switching behaviors with larger switching field variation while the junction...
