A compact charge-based physical model for AlGaN/GaN HEMTs

摘要

This work presents a physical compact model for AlGaN/GaN HEMT devices. An analytical model of the drain current has been developed based on models of the charge density in the 2DEG channel but considering only a single energy level. The approach resulted in an accurate and simple current model. The model covers all the different operation regions of a device. Excellent agreements with measured I-V characteristics of a device have showed the validation of the model.
