Abstract
Artificial neural networks (ANNs)are presented for the fast and accurate modeling of passive and active devices in MMICs.ANNs trained with S-parameter over a wide range of frequencies were used for rectangular spiral inductor modeling and HEMT device small-signal models.After training and testing the ANN S-parameter model can be implemented as a two-port network into commercial circuit simulators.This enable the ANN model to be used in the design,analysis,and optimization of microwave circuits.A combination of ANN models trained with S-parameter and dc drain current measurements was implemented into an HP microwave circuit simulator to provide a small- signal bias-dependent active model.The proposed technique is capable of providing easy,fast and accurate simulation models for MMIC components where models based on equivalent circuit parameters (ECPs)do not exist or are not accurate over the desired region of operation.
