Abstract:
This article presents a volumetric integrated voltage regulator (IVR) based on a switched-capacitor-stack-inductor (SCSL) architecture that employs a holistic topology-control-package codesign to overcome the hardware and efficiency bottlenecks of conventional asymmetric multiinductor designs. Based on a discrete-time state-space model, a rigorous root-locus analysis reveals that a rudimentary single voltage-mode control …
