Some applications require an energy transfer without contacts and wires. The mutual inductive effects between two coils allow to transfer energy to an electronic consumer through an air gap. This paper presents an analytical model of a coreless transformer ...
In the domain of electronic devices and especially desktop peripherals, there is an industrial trend which consists in removing the cables that pollute our domestic and professional environments. In this sense, wireless communication protocols are already ...
Inductive Power Transfer (IPT) is well-established for applications with biomedical implants and radio-frequency identification systems. Recently, also systems for the charging of the batteries of consumer electronic devices and of electric and hybrid elec ...
A hybrid technology for the realization of threedimensional miniaturized power inductors, transformers and RF inductors is presented. This technology consists of combining planar Cu coils on polyimide substrates with high permeability and high resistivity ...
The growing demand for new technologies in several fields : recreation, medicine, transport, telecommunications and the space industry, etc. is increasingly related to the field of the management, transformation and use of electric power. In this domain, t ...
This paper presents the analysis of inductive links for remote powering of implantable devices and a method to improve the power link efficiency by modifying the geometrical parameters of planar spiral inductors. The analysis of the inductive links include ...
A contactless energy transfer system to supply computer peripherals is under development. It consists of an array of primary coils that are integrated in a table and secondary coils placed under the peripherals. For an everyday use, it is unthinkable to su ...
The development of very high-speed motors has evolved fascinatingly in the last few years. Due to their speed, their low weight and their high power density, the need for such motors has recently increased for various different applications. Among them, su ...
We present two fully differential limiting amplifiers with and without inductive peaking, designed and integrated in 0.18mm digital CMOS technology. The key design trade-offs, the importance of inductive coupling between neighboring channels, as well as th ...
Growing demand for the solid state meters for power and energy measurement leads to the fully integrated Hall sensor based microsystem solutions. In this paper we describe fully integrated SOI Hall sensor based microsystem for power and energy measurements ...
