Three fully integrated bandgap voltage references (BGVRs) have been demonstrated in a 4H–SiC bipolar technology. The circuits have been characterized over a wide temperature range from 25 °C to 500 °C. The three BGVRs are functional and exhibit 46 ppm/°C, 131 ppm/°C, and 120 ppm/°C output voltage variations from 25 °C up to 500 °C. This letter shows that SiC bipolar BGVRs are capable of providing...
A high temperature compensated voltage reference integrated circuit (IC), was designed and for the first time fabricated on silicon carbide (SiC) material, using MESFET devices. A planar finger type MESFET was developed for this purpose. The schematic and the principle of the presented circuit is based on a new concept that replace the typical bandgap reference and avoid the necessity of using an...
