Abstract
Gallium nitride (GaN) transistors enable efficient
and compact high-voltage power converters. In the state-of-the-
art enhancement mode GaN-on-Si technology, a 650-V power
transistor is formed as a lateral structure enabling monolithic
integration with a driver and analog control circuits on one die.
Offline power converters show a trend toward a higher level of
integration, shifting from monolithic silicon (CMOS) to various
integration levels in GaN technology. In this article, a monolithic,
self
