摘要

In this work, we present the analytical model of buck converter with 3-D in-package air-core inductor ( $150~\mu \text{m}$ thick). To optimize the power efficiency at a targeted power density, models including 3-D inductor and power switches are developed. Compared to 3-D electromagnetic (EM) simulation, the proposed inductor ...
