Fabrication and Testing of 4H-SiC MESFETs for Analog Functions Circuits
Lateral normally-on dual gates MESFETs withstanding a drain/source voltage in excess of 200V have been fabricated on semi-insulating 4H-SiC substrate. This paper reports on the fabrication, DC characterization and in-circuit behavior of the MESFETs. Temperature dependent DC characterization has been carried out up to 473K. The performances of basic analog circuits such as an amplifier and a clock, using these MESFETs, are detailed and analyzed.
