Planar spiral inductors are less expensive than eitherchip or coil inductors for PCB (printed-circuit-board)-based designs. Accuracy in designinga spiral inductor is important because it isdifficult ...
We report a fabrication technology for 3D air-core inductors for small footprint and very-high-frequency power conversions. Our process is scalable and highly generic for fabricating inductors with a ...
