Five different Hall Effect sensors were modeled and their performance evaluated using a three dimensional simulator. The physical structure of the implemented sensors reproduces a certain technological fabrication process. Hall voltage, absolute, current-r ...

Transient Stability Assessment (TSA) is the process in which the stability of a system is characterized qualitatively or quantitatively. The TSA algorithm presented in this paper is derived from the well-established Single Machine Equivalent (SIME) method ...

This paper presents a methodology for digitally calibrating analog circuits and systems. Based on the detection of an imperfection by a simple comparator, a successive approximations algorithm tunes a compensation current. The latter is generated by a sub- ...

In this paper, the partially depleted SOI phototransistor has been used as a light intensity sensor. A pixel implementing the technique elaborated in [1] was designed and implemented on SOI technology. The circuit implements a first order Delta-sigma modul ...

In the present work a punch-through impact ionization MOSFET (PIMOS) is presented, which exploits impact ionization in low-doped body-tied [Omega]- and tri-gate structures to obtain abrupt switching (3-10 mV/decade) combined with a hysteresis in the ID(VDS ...

Contactless current measurement based on Hall-effect sensors can be performed in either closed-or open-loop configuration. In this paper an open-loop sensor system with a current-mode output is described. The system measures the magnetic field induced arou ...

This paper presents the application of a complete digital calibration methodology to the improvement of a Hall sensor-based current measurement microsystem. It is a step-by-step illustration of how generic calibration techniques and circuits can be used on ...

In order to provide the information on their Hall voltage, sensitivity and drift with temperature, a new simpler lumped circuit model for the evaluation of various Hall Effect sensors has been developed. In this sense, the finite element model associated c ...

The stability and the dimensioning of a step-down switching voltage regulator feedback loop remain a complex task. An analytical approach allows dimensioning of all the components, strongly facilitating this task. In this article, a mathematical analysis i ...

The present paper focuses on evaluating the temperature effects on Hall Effect sensors sensitivity behavior. To this purpose, an analysis of the factors affecting the sensors current-related sensitivity is performed, consisting of several pertinent conside ...

Localizing, identifying and authenticating the individual occupants is of paramount importance for the future intelligent buildings. Although the performance of outdoor positioning systems is sufficiently good, the indoor ones have still to converge to a u ...

Mass sensing has so far rather developed along the resolution axis, reaching atomic-scale detection, than into the direction of high speed. This letter reports on a novel self-calibrating technique that makes high-speed inertial mass sensors capable of ins ...

This paper describes the analysis and design of a dynamic supply CMOS audio power amplifier for low-power applications. The dynamic supply technique is used to increase the efficiency of a class AB power amplifier. The polarization of its output stage is a ...
