Automotive electronics use high-power-density DC-DC converters that are required to withstand extreme operating temperatures up to 200°C. As depicted in the top left of Fig. 3.8.1, conventional bandgap and CMOS reference-voltage circuits have a lower operating temperature [1-8]. Although power consumption can be effectively reduced from 2.6nW [2] to 192pW [8], the reference-voltage circuits are not suitable for high-power-density applications due to the limited temperature range. For industrial GaN applications, the supply voltage needs to support a wide
