一种用于车载应用、具有自生成开关信号的全集成电感式GaN升压转换器

An inductor-based GaN dc-boost converter with self-generated switching signal is proposed to remove power and area consuming gate drivers for toggling a large transistor switch. All the active and passive components are integrated on a 3 mm ×3 mm die using 0.25-μm GaN-on-SiC process. The circuit operates at 680-MHz switching frequency with 0.24 W/mm2 power density at 20-V output voltage for vehicu...
