Abstract
To unlock the full potential of monolithic gallium
nitride (GaN) power integrated circuits, this article explores the
feasibility of developing efficient and reliable on-chip gate driving
and level shifting solutions, which fundamentally facilitate the on-
chip implementation of GaN power circuits. As results, a self-
bootstrapped hybrid (SBH) gate driving scheme and its circuitry
are developed, which achieve rail-to-rail dynamic gate driving in
normal operation and robust static gate driving in
