Abstract
This article presents a fully integrated voltage
regulator (FIVR) featuring a high power density, fast dynamic
voltage scaling (DVS), and self-balanced inductor currents. The
proposed two-phase 2L1C buck converter topology can 2×reduce
the number of power switches and flying capacitors (CF) com-
pared to the conventional two-phase three-level (2P3L) converters
while inheriting the benefit of a lower switching voltage. The
single-CF-based self-balancing of the inductor currents with
no extra over
