Compact Circuit Modeling of Nonlinear Dynamic On-Chip Magnetic Devices
The addition of thin-film alloy magnetic materials to integrated circuit processing enables a number of novel integrated circuits. Examples are the essential devices in fully integrated magnetic field sensors and power supplies on chip (PwrSoC). There are several benefits to integrating these traditionally off-chip devices, including improved manufacturability, reduced cost, and saving board space. Traditional on-chip models for these devices do not accurately capture certain determinative performance figures in their respective applications, such as saturation dynamics and AC power loss. In this work, a novel physics-based model topology that captures nonlinear dynamics is employed. The model parameters are extracted from readily obtained on-wafer device measurements through a unique hierarchical extraction algorithm. Ultimately, this research enables accurate circuit simulations of novel on-chip magnetic devices potentially realizing first pass design success.
