چکیده :

Hybrid Resonant Switched-Capacitor (HRSC) converters present a promising approach for achieving high energy density and efficient voltage regulation in integrated power systems, as they combine the advantages of capacitors and small inductors. Although a few works have explored optimal passive sizing in discrete implementations, comprehensive strategies for minimizing total on-chip area in fully integrated designs are still lacking. In this paper, we present an analytical and simulation-based methodology to minimize the total on-chip area of inductors and capacitors in HRSC converters. Electromagnetic simulation is used to accurately model integrated inductor performance. Comparative results demonstrate that, under realistic constraints, the optimized hybrid topology achieves substantially lower total on-chip passive area than a conventional Buck converter. The effect of passive component losses on passive area optimization is also investigated.
