Inhalt:
This paper proposes a new bias-dependent description for the Pospieszalski noise model for GaN HEMT devices. It is also proposed to replace the traditional description of the drain noise temperature by a general noise power which is linked to the drain current. A well-behaved bias dependence of the new parameter is found and we were able to show that the new approach reduces uncertainty in the nonlinear noise model.
