A novel extraction methodology is proposed to distinguish between the extrinsic and intrinsic capacitances of wide GaN HEMTs. This approach is based on the experimental observation that the real parts of the impedance parameters of such devices increase at high-frequency. The mathematical analysis clearly shows that this so far uninvestigated behavior can be attributed to the extrinsic capacitances.

Abstract
A novel extraction methodology is proposed to distinguish between the extrinsic and intrinsic capacitances of wide GaN HEMTs. This approach is based on the experimental observation that the real parts of the impedance parameters of such devices increase at high-frequency. The mathematical analysis clearly shows that this so far uninvestigated behavior can be attributed to the extrinsic capacitances.File in questo prodotto:
