一种用于包络跟踪放大器的带反自举电平转换器的单片GaN DC-DC降压转换器

DC–DC buck converters have become a key module for improving the overall efficiency of modern communication systems. This article reports a novel monolithic GaN dc–dc buck converter with an integrated power stage and driver for envelope-tracking applications. An antibootstrap level shifter with a power consumption of nearly zero is proposed for the first time to effectively reduce the driver power...
