26.5 An Inductor-at-Middle Hybrid Buck Converter with Shared Power-Signal Path for Distributed Vertical Power Delivery
Abstract
This work presents an inductor-at-middle hybrid buck converter for high-current density vertical power delivery, reusing the power inductors as signal feedback paths. The proposed switching-bus-multiplexing control reuses the power path to carry a feedback signal, mitigating the challenges in sophisticated signal and power network co-design for pinintensive distributed power delivery networks. The prototype achieves a vertical current density of$3.17 \mathrm{A} / \text{mm}^{2}$.
