Coupled inductors can be used as tunable inductances. Employing coupled inductors in the output impedance matching network of an RF power amplifier leads to superior performance when operating in more than one frequency band. As proof of this concept, the ...
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 ...
The reliability of systems made of unreliable nanoelectronic devices is discussed in this paper. Massive defect density which may affect future fabrication technologies calls for novel solutions, where spatial redundancy and the voting scheme play a signif ...

A storage supercapacitor subsystem is studied for insertion in a series hybrid electric vehicle (Fig. 1). This subsystem is composed of a supercapacitor bank and a braking resistor used when the supercapacitor voltage is at its maximum value. Generally, wh ...
We expose the past and present state-of-the-art of Micro-ElectroMechanical System (MEMS) inductors. Starting from the basic inductor equations, we discuss the various material and frequency-dependent loss mechanisms that contribute to a decreasing quality ...

During the last years, permanent magnets synchronous motors have become a reference in the industrial world, both from the economical and the technical point of view, because of their very good performance in both regards. Thus, application of specific met ...
A technique to deterministically manipulate individual Carbon Nanotubes (CNT) has been the brick-wall for the boom of CNT based devices. Here we demonstrate dielectrophoresis as an efficient technique to trap individual Single Walled Carbon Nanotubes (SWCN ...
In this paper we present an RF PA employing an output impedance matching network of the pi-type, where an inductor is variable. In order to implement this tunable inductor, the coupled-inductor technique [1] is used. Although other techniques for inductor ...
In this paper, we present the giant-magneto-impedance (GMI) effect in a microfabricated closed Permalloy core which surrounds a copper excitation rod. We measured a 90% change in the inductance value of the device for a sinusoidal excitation at 500 kHz in ...
We present a general metallization process for the fabrication of solenoidal micro-coils for high resolution MRI of volume-limited samples. The process allows for the MEMS-compatible batch fabrication of identical coils. Hollow conductors are integrated wi ...
