In this research, the operation of differential amplifier based on 4H-SiC MOSFETs at temperature up to 500℃ was investigated. Based on the I_D-V_G, and I_D-V_DS characteristics measured at 500℃ indicated that, with our fabrication process, the 4H-SiC MOSFETs had ability to operate in high temperature ambient. Whereas, the stability of the output signal of the amplifier conducted at 500℃ showed that the integrated circuit based on 4H-SiC MOSFETs could operate well at 500℃. This research demonstrated that the integrated electronic circuit based on 4H-SiC MOSFET technology is promising for high-temperature applications.
