In the last decade, hybrid and resonant switched-capacitor (SC) converters have gone from a relatively unexplored concept to one that is gaining widespread adoption in a range of applications [1]. However, despite capabilities to operate efficiently with small passive components, extending these topologies to use silicon-integrated inductors remains challenging [2-6]. This work presents a nominally 3:1 step-down resonant Dickson converter targeting low-voltage applications and providing several advances compared to past work. Shown in Fig. 18.4.1, the design uses a merged electromagnetic spiral resonator. As in [3], the merged resonator combines flying capacitance and inductance into a single structure. Shared die area reduces size overhead but also provides current ballasting which counteracts strong high-frequency (skin and proximity) loss effects, enabling high-frequency operation with better efficiency and power density.
