Modeling special high frequency devices using artificial neural networks

Nowadays, there are miscellaneous types of high frequency devices for which their models for CAD are necessary. However, in the majority of standard programs for RF design, only a class of MESFET models is available. These models are sufficiently accurate for usual devices; however, they are insufficiently accurate for modeling special high frequency devices. In paper, a method is proposed for modeling the special devices using exclusive or corrective artificial neural networks.
