abstract = "This paper presents a feedback circuit topologies based on AlGaN/GaN (Aluminum Gallium Nitride / Gallium Nitride) MIS-HEMT (Metal Insulator Semiconductor High Electron Mobility Transistor) to address the issue of abnormal output ripple in DC-DC buck converters and mitigate voltage overcharge at the operating point. The proposed circuit structure is simulated and calibrated using the ADS (Advanced Design System) platform. Subsequently, the circuit's output characteristics and principles of the optimized bootstrap comparator are analyzed. The results show that the maximum output voltage fluctuation is 0.05 V and the average fluctuation is less than 0.5 %, providing references and suggestions for the feasibility and application potential of the buck converter circuit structure in monolithic integrated GaN power converters.",
