Abstract :
A scalable HEMT noise model has been developed, based on a lumped parasitic network extracted analytically through full-wave electromagnetic simulations and a scalable black-box representation of the intrinsic noise and AC response of the device. The analytical extraction of the lumped parasitic network is extensively explained, as well as the intrinsic model identification. The model prediction capability, in terms of S-parameters and noise performance, has been validated through the scaling of two different HEMTs.
