Abstract
This paper introduces a fundamentally different
type of switched-capacitor dc–dc converter with large voltage
swing flying capacitors, which is made efficient using advanced
multiphasing soft charging. A single-capacitor topology is derived
that behaves like a gyrator and achieves a continuously scalable-
conversion-ratio with high efficiency. A circuit fabricated in a
28-nm CMOS process demonstrates the working principle of the
presented topology and advances the state of the art by achieving
