| 内容記述 | In recent years, research on silicon carbide (SiC) devices and integrated circuits intended for operation in harsh environments such as high-temperature and radiation-rich conditions has been actively conducted. In this study, the gain stage intended for use in an operational amplifier (op-amp) composed of SiC junction field effect transistors (JFETs) was operated while gamma-rays irradiation up to 1MGy, and changes in bode plot were evaluated. No degradation was observed in the frequency characteristics of the voltage gain and phase of the gain stage after irradiation. In addition, another SiC op-amp with a more practical design with a common-centroid JFET layout and two-layer interconnects was also fabricated. It operated as a non-inverting amplifier, though its bandwidth was limited. | |||||||||||||||||||||||||||
