A method is presented for including motional and eddy current effects when analytically modeling electrical impedance functions of cylindrical magnetostrictive transducers. To approximate eddy current effects, one-dimensional analytical constant parameter linear electromagnetic models of a cylindrical magnetostrictive transducer are developed. Maxwell's equations are solved for the magnetic fie...

In this paper, a low-power adaptive low noise amplifier (LNA) is presented. The LNA is based on a bipolar cascode topology, uses inductive source degeneration and emitter area scaling to achieve noise and input-impedance matching simultaneously. The input impedance and the noise factor were simulated as function of the bias collector current and the results show that both are approximately cons...

We study an optimized numerical method for solving the forward problem of the two-dimensional Impedance Equation. Based upon elements of the modern Pseudoanalytic Function Theory, its performance is tested employing sinusoidal conductivity functions within the unit circle. Then a collection of experimental data are displayed for illustrating its effectiveness. The work closes with a brief discu...

This paper describes the optimization of the measurement time of the impedance frequency response of a vibrating wire sensor for viscosity estimation. The optimization deals with the assessment of the estimated viscosity as a function of the number of measured impedance frequency points as well as the selection of those frequencies. This speed optimization is important to ensure that the viscos...

Here we propose and analyze the behavior of a FET–like switching device, the Mott transition field effect transistor, operating on a novel principle, the Mott metal–insulator transition. The device has FET-like characteristics with a low “ON” impedance and high “OFF” impedance. Function of the device is feasible down to nanoscale dimensions. Implementation with a class of organic charge transfe...

electrochemical impedance spectroscopy (eis) is a suitable and powerful diagnostic testing method for fuel cells (fcs) since it is non-destructive and provides useful information about fc performance and its components. in this study, for the first time, a 500w cascade type 4 cells stack with integrated humidifier, water separator and internal manifolds was designed, fabricated and tested. the ...

THIS paper focuses on MIMO Power Line Communication (PLC) to provide increased performance. In MIMO PLC, appropriate coupling methods are necessary in order to enable the effective injection of the signal through the broad band PLC channel so that high data rates can be achieved [1], [2], [3]. In the literature, different kind of couplers are proposed [4],[5]. In this paper, we want to characte...

A new high input impedance voltage-mode universal biquadratic filter with three input terminals and five output terminals is presented. The proposed circuit uses three plus-type differential difference current conveyors, two grounded resistors and two grounded capacitors. The proposed circuit can realize all the standard filter functions: lowpass, bandpass, highpass, notch and allpass, without ...
