Abstract
- Air-core slab inductors with specially designed current return paths are proposed to achieve the ultra-high Q required for on-chip power delivery and management at >90% efficiency. Uniquely optimized for buck converter circuits, this CMOS-compatible structure avoids the challenges of thin-film magnetics. Q∼25–30 at 200–300MHz is experimentally demonstrated.
