This paper proposes a fast and accurate order reduction algorithm for the extraction of compact macromodels for electrostatic actuated micro-electro-mechanical (MEMS) switches used in radio-frequency (RF) applications. The algorithm uses as input the information obtained from field simulations, in which coupled equations of electrostatic, structural-dynamic, air flow and full wave electromagnetic...
This contribution refers to a methodology for the extraction of RF macromodels for electrostatically actuated switches. The extraction is based on the results obtained from three RF simulations carried out at the device-level model, with the finite integration technique, and use of a fitting procedure based on closed form relationships for the TL-lumped macromodel. Two test configurations were studied...
This paper proposes the use of coupled electric and magnetic circuits in the schematic models of high frequency integrated circuits, as an effective method to model the global inductive effects and coupling. These pairs of coupled circuits, called magneto-electro-equivalent circuit (MEEC) models, are obtained by partitioning the computational domain into several subdomains, each having its own electromagnetic...
This paper describes an original methodology for the modeling of parasitic inductive couplings. The key idea is the use of magnetic hooks which are gates for magnetic fluxes that cross conductive loops and consequently induce parasitic voltages, thus disturbing the signal integrity. The multiple connected domains of integrated circuits are modeled by a Magneto-Electric-Equivalent-Circuit (MEEC), consisting...
A modeling approach based on domain partitioning and use of the electromagnetic circuit formulation for full wave electromagnetic field is applied for high frequency integrated passive components, including MEMS switches. The procedure is completed by model order reduction and generation of a small compact model that describes with high accuracy the input-output behavior of the device. The main benefit...
This paper investigates two methods of exploiting parallel architectures in order to efficiently extract reduced-order models for passive high-frequency integrated devices. Due to the high frequencies involved, all the effects of electromagnetic fields must be taken into account, but this leads to very large models which have to be reduced. We use an efficient technique, based on Vector Fitting, to...
In this paper, a modeling approach appropriate for the homogeneous sub-domains in integrated circuits is proposed. This modeling approach can be applied if an exponential decay of the field variation can be assumed as it happens in the substrate and in the air above the chip. The main idea is to perform a hierarchical modeling based on an exponential partitioning scheme of the homogeneous layer, conducing...
