A 3-D glass embedded inductor and application in power converter

A glass embedded inductor is proposed in the paper and the impact of material properties and physical parameters on the electrical performance of the inductor is investigated. The glass-based inductor is then adopted in a step-down power converter. Due to high quality factor of the proposed inductor, the power converter with glass inductor shows a high-power efficiency than that with silicon-based inductor. The results would provide some guideline for circuit design on glass-based interposer.
