Abstract: Resonant switched-capacitor (ReSC) converters have efficient utilization of both active and passive components, and hold the potential to achieve higher efficiency and higher power density than conventional switched-capacitor (SC) and magnetic-based converters.
However, recently developed hybrid-resonant switched capacitor (SC) topologies may be promising when combined with spiral magnetics, e.g., , , as they leverage higher-density on-chip capacitors while reducing the size and energy storage requirements of inductors.
This article presents a new hybrid/resonant SC converter topology, comprising two cascaded 2-to-1 ReSC converters, to address high-conversion-ratio applications. The proposed cascaded resonant converter has a simple structure and operation principle and can achieve one of the best overall metrics among popular ReSC topologies.
Switched-capacitor (SC) converters have shown promise in this regard due to relatively high energy-density of capacitors and favorable device utilization figures of merit.
Finally, a chip-scale ReSC converter is presented that can deliver over 4 W at 0.6 W/mm 2 with 85% efficiency. The two-phase, nominally 2:1 converter supports input voltages from 3.6-6.0 V, and is implemented in 180-nm bulk CMOS with die-attached air-core solenoid inductors.
Planar spiral inductors are attractive from an integration perspective, but tend to have low inductance and energy-storage capability, low quality factor in mid-MHz frequencies, and high skin, proximity, and substrate-loss effects [1-3].
An HSs method using self‐resonant capacitor integrated in the output matching network of HPA is proposed to improve the HSs characteristics.
