An Equivalent Circuit Model for On-chip Inductors with Gradual Changed Structure
نویسندگان
چکیده
Inductor with gradual changed metal width and space by good design can get better Q factor than the inductor with fixed metal width and space. In this paper, a simple wide-band inductor model is presented considering both the increase of resistance and the decrease of inductance due to the skin and proximity effects. This model has been verified with simulation and the experimental results of spiral inductors with various geometrical configurations on high-resistivity silicon substrate. Good agreements have been achieved under the selfresonance frequency, which indicates its accuracy. This model has also been proved to be suitable for both the conventional inductor with fixed structure and the inductor with gradual changed structure.

The accurate simulation of the electromagnetic behaviour of interconnects and on-chip inductors is becoming more and more important for chip designs. For this purpose, we investigate the use of the electric field integral equation, which can be used to construct a full-wave electromagnetic model.

This paper proposes an optimization methodology of on-chip spiral inductors. Characteristics of spiral inductors heavily depend on layout structures. We then formulate the characteristics with structural parameters and frequency as variables using a response surface method. The proposed method uses S-parameters to express inductor characteristics, and hence our method is independent of spiral g...
متن کاملA New Analytical Approach for Developing an Equivalent Circuit Simulation Model for a Chip Inductor, Based on Manufacturer Specifications Given in the Datasheet
Inductors represent a very complex behavior especially in the field of RF techniques. Some manufacturers offer SPICE models for their inductors built up by lumped elements. The lumped element values are determined by matching the simulation model to an average of the measurements. This leads to curious numbers, and if the model is used in a simulation tool, all these values have to be adjusted ...
