RF-MEMS inductor is a crucial component in radio-frequency integrated circuits (RFIC). partial element equivalent circuits(PEEC) method is used to model a spiral inductor as a two-port equivalent lumped circuit. Numerical examples showed that the method is easy implemented and accurate in analysis of both planar and three-dimensional inductors.

This paper presents a new modeling technique, entitled extended MagPEEC model, which can be used to simulate arbitrary three-dimensional conductor-magnet structures of any geometry with direct conductor-magnet interfaces included. The new model was validated using a sample coaxial transmission line structure and was applied to investigate a group of super compact sixlayer stacked spiral radio frequency integrated circuits (RFICs) inductor structures with various magnetic media integrated inside. This new modeling technique can be used to assist design of complex conductor-magnet structures including various magnetic-enhanced inductors for RFIC applications.

Rotary clocking is a resonant clocking technology for clock network design and distribution in high performance digital VLSI circuits. Rotary clocking technology offers an attractive alternative to the conventional clocking with high frequency clock signal generation at a low power dissipation rate. Traditionally, rotary clocking has been implemented using a regular array (grid) topology called rotary oscillatory arrays (ROA). In this paper, a custom rotary oscillatory array (CROA) topology is proposed for the generation and distribution of rotary clocking. The issues related to timing closure are addressed and the simulation-based analysis of the custom rotary rings is presented. The CROA design methodology is tested on the IBM R1-R5 benchmark circuits. Compared to the traditional ROA, custom ROA results in 39.25% of tapping wirelength savings. The parasitic effects due to the customization of the topology-computed with partialelementequivalent circuit (PEEC) analysis-are incorporated and the CROA topologies are simulated in SPICE. The simulation results show that, with additional parasitics due to the topological factors, the resultant clock frequency is observed to be 8.79% slower (assuming the tapping wirelength remains the same) than the expected frequency of operation without considering the topological factors.

The busbars in high power neutral point clamped three-level inverters are modeled using the Maxwell Q3D Extractor software, which is based on the partial element equivalent circuits method. The equivalentcircuits of the busbars and devices model are simulated in the electric simulator PSlM to analyze the effects of the parasitic inductance on the switching characteristics of the integrated gate commutated thyristor （IGCT） in different topology positions. The simulation results agree well with the measured impedance analyzer results and the IGCT test results, which proves the effectiveness of the modeling method for the large, complex busbars.

An accurate model is presented for micromachined on-chip spiral inductors, in which the high-frequency current crowding effects in metal traces are considered by simplified partial element equivalent circuits, and the substrate parasitics are extracted by the parametric modeling method. The model has been confirmed by both measurements and the results from the 3-dimensional finite element method. This equivalent circuit model enables the prediction and optimization of high-Q micromachined spiral inductors in gigahertz frequencies. (C) 2003 Wiley Periodicals, Inc.
