A 3-d hybrid Jiles-Atherton/Stoner-Wohlfarth magnetic hysteresis model for inductive sensors and actuators
Dimitropoulos, P. D.; Stamoulis, G. I.; Hristoforou, E. (2006)The Jiles-Atherton (JA) theory of hysteresis is currently used in the majority of commercial CAD tools, mainly due to its implementation simplicity in fast and stable algorithms. The JA model provides precise results in ... -
A completely scalable lumped-circuit model for horizontal and vertical HALL devices
Dimitropoulos, P. D.; Reymond, S.; Drljaca, P. M.; Popovic, R. S.; Nastos, N. (2007)A completely scalable lumped-circuit model for horizontal and vertical HALL devices is presented therein that can be efficiently implemented in SPICE-like EDA simulators. The model has been employed for the quantitative ... -
Galvanomagnetic effects "Sensors based on hall effect"
Petousis, V. N.; Dimitropoulos, P. D. (2009)The Hall effect is the generation of a transverse electromotive force in a sample carrying an electric current and exposed to perpendicular magnetic field. Depending on the sample geometry, this electromotive force may ... -
General development of a new hall effect sensor
Petoussis, V. N.; Dimitropoulos, P. D.; Stamoulis, G. (2011)Silicon Hall plates show an offset of a few millitesla. A large portion of this offset is caused by mechanical stress in the device. The offset can be reduced with a factor 103 to 105 when the spinning - current principle ... -
A hybrid Jiles-Atherton / Stoner-Wohlfarth magnetic hysteresis model for inductive sensors and actuators
Dimitropoulos, P. D.; Stamoulis, G. I.; Hristoforou, E. (2004)The Jiles-Atherton (JA) theory of hysteresis is currently used in the majority of CAD tools. The JA model provides precise results in the case of poly crystalline, multi-domain magnetic structures, whose flux-reversal is ... -
A low-power/low-noise readout circuit for integrated capacitive sensors
Dimitropoulos, P. D.; Karampatzakis, D. P.; Panagopoulos, G. D.; Stamoulis, G. I. (2006)A switched-capacitor integrated system is presented in this work that attains sub-fF measurement resolution in integrated capacitive sensors, with 1.5-kHz bandwidth and 50-mu W average power consumption in continuous ... -
A new SOI monolithic capacitive sensor for absolute and differential pressure measurements
Dimitropoulos, P. D.; Kachris, C.; Karampatzakis, D. P.; Stamoulis, G. I. (2005)In the present work, a new monolithic capacitive pressure sensor is being introduced. The sensor is manufactured according to a custom, 15-step SOI process. The process primarily offers great flexibility as far as sensor ... -
Noise sources in miniature flugate sensors. Part II: the case of sensors with Fe77.5Si7.5B15 amorphous wire cores
Dimitropoulos, P. D. (2005)As a continuation of Part I this paper is devoted to fluxgate sensors that employ Fe77.5Si7.5B15 amorphous wires as magnetic cores, with attention being paid to fluxgate miniaturization. Two types of fluxgate sensors have ... -
Noise sources in miniature fluxgate sensors Part I: theoretical treatment
Dimitropoulos, P. D. (2005)A mathematical model for miniature fluxgate magnetometers is presented in the first part of this work. It is based on certain well- defined and easy- measurable parameters of the hysteresis loop exhibited by the fluxgate ... -
On a new principle of a smart multisensor based on magnetic effects
Hristoforou, E.; Hauser, H.; Dimitropoulos, P. D. (2006)In this paper, a new principle of a smart sensor is proposed, based on three different magnetic effects or operational modes, using the same sensor topology, which consists of a magnetic wire as sensing core, two coils as ... -
RFID middleware design for enhancing traceability in the supply chain management
Zarokostas, N.; Dimitropoulos, P. D.; Soldates, J. (2007)Inventory tracking is an emerging trend in various industries that can significantly improve asset utilization using real-time information about products location and condition. The adoption of RFID technology in inventory ... -
Triggering and data collection framework for sensing application level events
Zarokostas, N.; Dimitropoulos, P. D.; Soldatos, J.; Stamoulis, G. (2012)In this paper we propose an interface between the various automatic identification devices and the filtering and collection role proposed by the EPCglobal architecture. This interface, namely the read cycle report interface, ...
