Optimization of magnetic enhancement layers for high-frequency stripline micro-inductors

An analytic model for stripline micro-inductors is presented which accurately approximates finite-element solutions while also allowing for variation of a wide range of parameters. Optimized models for magnetic enhancement layers are validated with measured results of different materials. The effects of these device and material models are applied to analyze stripline devices operating above 100 MHz. The effects of geometry on inductance, Q-factor, and current-carrying capability are presented for the materials in question.
