| Outline of Final Research Achievements |
We developed a mixed-signal ASIC for low-noise high-speed signal processing of onboard X-ray CCD cameras as well as dedicated printed circuit boards. While its noise performance was almost the same as that of the last version of ASIC that have been used for CCD camera onboard X-ray astronomical satellite Hitomi, the linearity performance improved (INL=0.1%, corresponds 6eV deviation at 6keV). We also verified the statistical radiation tolerance of our ASIC in terms of total ionizing dose and single event latch-up in the low earth orbit.
