A new nonquasi-static nonlinear model of electron devices is proposed by adopting a perturbed charge-controlled approach. The model is based on the definition of a virtual quasi-static device, associated with the actual one, which is controlled by means of equivalent voltage sources. The advantage of this approach is that conventional purely quasi-static models can be still adopted even at very high frequencies, if suitable equivalent voltages are applied. Identification from small-signal measurements and implementation into commercially available computer-aided design tools of the new nonquasi-static model are described in this paper. Finally, by considering a GaAs p-high electron mobility transistor, accurate prediction capabilities at microwaves and millimeter frequencies are experimental verified and compared with a more conventional equivalent-circuit-based model.

Abstract: | A new nonquasi-static nonlinear model of electron devices is proposed by adopting a perturbed charge-controlled approach. The model is based on the definition of a virtual quasi-static device, associated with the actual one, which is controlled by means of equivalent voltage sources. The advantage of this approach is that conventional purely quasi-static models can be still adopted even at very high frequencies, if suitable equivalent voltages are applied. Identification from small-signal measurements and implementation into commercially available computer-aided design tools of the new nonquasi-static model are described in this paper. Finally, by considering a GaAs p-high electron mobility transistor, accurate prediction capabilities at microwaves and millimeter frequencies are experimental verified and compared with a more conventional equivalent-circuit-based model. | |
