Title (EN) SYSTEM FOR SIGNAL DETECTION OF SPECIMEN USING MAGNETO RESISTANCE SENSOR
(FR) SYSTÈME DE DÉTECTION DE SIGNAL DE SPÉCIMEN UTILISANT UN CAPTEUR MAGNÉTORÉSISTIF
Abstract: front page image
(EN)Provided is a detection system using a magneto resistance sensor. In particular, the magneto resistance sensor includes an amplification driver amplifying a detection signal supplied from a detection device including a magneto resistance sensor and sensing only a magnetic signal during the application of magnetic field, wherein the amplification driver includes an AC amplification circuit having at least one capacitor disposed at an back end of an input of the magneto resistance sensor to which the detection signal is input.
(FR)L'invention porte sur un système de détection utilisant un capteur magnétorésistif. En particulier, le capteur magnétorésistif comprend un circuit d'attaque à amplification amplifiant un signal de détection appliqué par un dispositif de détection comprenant un capteur magnétorésistif et détectant seulement un signal magnétique durant l'application de champ magnétique, le circuit d'attaque à amplification comprenant un circuit d'amplification CA comprenant au moins un condensateur agencé au niveau d'une extrémité arrière d'une entrée du capteur magnétorésistif auquel le signal de détection est appliqué.
