Wideband modeling of RF circuits using automatic physical augmentation

A new wideband physical augmentation based modeling technique is proposed. In this method, all series augmentation elements are transformed into the parallel ones. Using this technique, the preliminary analysis of the circuit to decide the augmentation type is not needed. The type of augmentation to be performed can be determined automatically. The proposed methodology has been validated for broadband modeling of a spiral inductor and an MIM capacitor which shows good correlation with the EM data.
