This paper presents a methodology to design and to optimize inductive power link for biomedical applications. The importance of the operation frequency on the application is expressed. A model of inductive link is presented. The dimensions of the coils are compatible with the size of a mouse and the mouse cage. The simulation results are in good agreement with the analysis.
This brief presents a new structure of active inductors. These synthetic inductors are designed using current controlled voltage sources. The signal flow graph method is used for this purpose. For the practical realization, operational transresistance amplifiers (OTRAs) are replicated using current conveyors. The proposed inductors have very interesting properties because the value of its inductance...
Inductors play an essential role in the design of RF circuits. The parasitic effects plaguing integrated planar inductors require an accurate modeling and the careful exploration of their performance trade-offs. In this paper, a multi-objective performance modeling technique of planar inductors is presented, that supports both top-down and bottom-up design of RF circuits.
This paper addresses the automatic generation of RF integrated inductors model. In this work the double p-model is used as a way of characterizing the inductor behaviour over a frequency range beyond the self-resonant value. For the evaluation of the model element values analytical expressions based on technology parameters as well as on the device geometric characteristics are used. The use of a...
The paper presents a self-consistent semi-classical model describing the electrical behavior of carbon nanotube interconnects. The model deals with the general case of arbitrary chirality and takes rigorously into account the effects of nanotube size and chirality on its electrical parameters. The general model includes as particular cases the models currently used in literature to describe metallic...
This paper presents two monolithic transformer structures exhibiting high self resonance frequencies(fSR). Effect of positive and negative coupling factor on self resonance frequency is investigated. The transformer turn ratio and structure is selected to improve design and ease layout of a high frequency LNA and VCO. Measurement results of a transformer show good agreement with simulated values and...
As operating frequencies increase in state-of-the-art wireless designs, highly accurate modelling of critical interconnect paths routed over silicon is crucial for first-pass design success [1]. With this in mind, the interconnect stack of an IBM silicon germanium (SiGe) process incorporating a TSV ground supply network was modelled with model accuracy and efficiency as the goals. A unique modelling...
Nowadays, characteristics analysis of doubly salient electro-magnet machine is mostly about starter or generator separately, while transient characteristics of switching from starter to generator are less studied. Process of switching from starter to generator is an important part of the whole starter/generator system. In this paper, integral MATLAB model of doubly salient electro-magnet starter/generator...
To increase the output dynamic response and decrease the stable ripple of VRM, With multi-core combination, a split-phase coupling array integration inductance (short for SCAII) is applied in the four-phase VRM. Without considering the impact of leakage magnetic flux, the effect of SCAIIpsilas parameters is analyzed on the performance of VRM. The SCAIIpsilas complanation structure, is given and using...
The electric energy supply is necessary for different moving systems. Classical energy transfer is realized by flexible cables or slip rings, which are usually becoming weakness or performance limitations of the system. The contactless inductively coupled power transfer is a kind of new power transfer technologies. The electromagnetic induction technique has been used to achieve wide range power transfer...
In this paper, FE based circuit model is incorporated into systematic state space model to investigate the transformer inner behavior and characteristics of a saturated transformer type solid state fault current limiter (SSFCL). With novel design strategy for the proposed transformer, the FCL has small volume, low cost, and limits the short-circuit current substantially.
Modeling the grounding circuit with adequate accuracy is significant for studying conducted EMI problems caused by impedance of grounding net, while few researches has been done in this field. A simplified grounding model is introduced in this paper to represent grounding net. Several methods, including PEEC (partial element equivalent circuit), Ansoft Q3D, Maxwell 3D and FastModel are used to extract...

The electrostatic discharge (ESD) sensitivity of integrated circuits with respect to the charged device model depends strongly on the package. Electrical characteristics of a package are, if at all extracted, application specific. They depend on the environment e.g. the PCB. This paper characterises the package for the 1st time taking into account the CDM tester environment. The extracted parameters...
