| Research Abstract |
We designed and fabricated a mixed analog ASIC(Application-Specific Integrated Circuit) aimed for high-speed low-noise signal processing of X-ray CCD camera. It functioned with low noise at the speed of about 10 times faster than the electronics of the conventional cameras. The radiation tolerance tests using protons and heavy ions showed the sufficient hardness at the low earth orbit. X-ray spectrum was obtained using CCD and the ASIC, which verified the proper function of the ASIC as the signal processing circuit.
