　　A scalable large-signal model of AlGa N/Ga N High electron mobility transistors（HEMTs）suitable for multi-harmonic characterizations is presented.This model is fulfilled utilizing an improved drain-source current（Ids） formulation with a geometry-dependent thermal resistance（Rth） and charge-trapping modification.The Idsmodel is capable of accurately modeling the highorder transconductance（gm）,which is significant for the prediction of multi-harmonic characteristics.The thermal resistance is identi...
