Description

See more compact models using the MIT Virtual Source (MVS) Model

The MVSG-HV model is a physical model for HV-GaN HEMTs that includes formulations for currents and charges that can be used for HV circuit simulations. The model includes the effect of source and drain access regions, field plates: currents and charges, gate leakage, and self-heating effects.

The model in this release has been benchmarked against fabricated device IV- and CV- measurements with the model parameters provided along with benchmarked data. The optimization routine setup in ICCAP(commercial simulator) is also provided.

Circuit-level validation of the model is performed against a commercial HV- converter board and the simulation bench files along with the model and circuit-measurement results are included in the release.

The manual for the model and the simulation results are provided.
