“…If this middle part represents an RF block and not one component, then it is recommended to do also a horizontal partitioning of it. Thus, the interconnects can be treated as transmission lines, as we presented in [21], conductors can be modeled only with a MQS regime, passive components can be modeled independently in the modeling flow including model order reduction procedures as shown in [22], whereas active components are replaced by circuit models that take into account nonlinearities and drift-diffusion phenomena such as the one described in [23].…”

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 field regime. The model reduction method we propose can be used not only to derive the full coupled electric and magnetic circuit model of a device starting from its layout, but also to correct the electric schematic by adding inductive parasitic effects. The MEEC approach uses special boundary conditions-called magnetic/electric hooks-on the interfaces between the subparts in which the computational domain is partitioned. The success of the correct extraction of inductive effects rely on the terminal reduction, i.e., the correct placement of magnetic hooks on the interfaces. In order to find this placement, a heuristic approach based on IC layout analysis is proposed. In order to consider the parasitic inductive couplings, the electric schematic circuit graph is enhanced with geometric information from the layout (e.g., node coordinates). The MEEC-based approach is validated for a real example of a low noise amplifier. Its initial layout design proved to be wrong only after the fabrication and characterization of the first prototype. The use of the inductive parasitic extraction tool, based on the MEEC approach, would have prevented this. MEEC is an alternative approach to vector potential equivalent circuit, with respect to which advantages and disadvantages are discussed.Index Terms-Domain partitioning, electromagnetic (EM) circuit element, inductance extraction, magnetic hooks, magnetoelectro-equivalent circuit (MEEC), model order and terminal reduction, planar inductors, RFIC.

A novel circuit topology for inductive coupling between interconnecting wires is presented. The model is local, i.e., only coupling between neighboring wires is explicitly modeled. However, the topology accounts for long-range coupling by propagating the vector potential from one wire to the next. Examples of model calibration, both directly from layout and as model-order reduction of a given inductance matrix, are presented for simple wiring structures.
