N2 - Wide-bandgap gallium nitride devices offer a high critical field, good thermal conductivity, and fast switching, enabling high-voltage, high-Temperature applications. This work introduces a generic multi-loop regulated voltage reference topology on a monolithic AlGaN/GaN MIS-HEMT consisting of a D-mode and multiple E-modes. A 4-Transistor implementation produces a stable 2.33 V Vref across a 2.8∼50 V VDD supply while achieving an extremely low line sensitivity of 1.27×10-10 %/V. Closed-form analytical expressions for reference voltage, line regulation, and start-up voltage are derived to reveal parameter dependencies. These analytical results provide systematic guidance and practical design insights for GaN-based voltage references in highvoltage sensor biasing, power-integration modules, and nextgeneration intelligent power converters.
