Title (EN) CIRCUITS AND METHODS USING ADJUSTABLE FEEDBACK FOR SELF-CALIBRATING OR SELF-TESTING A MAGNETIC FIELD SENSOR WITH AN ADJUSTABLE TIME CONSTANT
(FR) CIRCUITS ET PROCÉDÉS UTILISANT UNE RÉTROACTION RÉGLABLE D'ÉTALONNAGE AUTOMATIQUE OU D'AUTOTEST D'UN CAPTEUR DE CHAMP MAGNÉTIQUE AVEC UNE CONSTANTE DE TEMPS RÉGLABLE
Abstract: front page image
(EN) A magnetic field sensor includes a reference-field-sensing circuit channel that allows a self-test or a self-calibration of the circuitry of the magnetic field sensor. The self-test or the self calibration can have at least two different bandwidths that provide a respective at least two different rates of self-test or self-calibration.
(FR) La présente invention concerne un capteur de champ magnétique comprenant un canal de circuit de détection de champ de référence qui permet un autotest ou un étalonnage automatique des circuits du capteur de champ magnétique. L'autotest ou l'étalonnage automatique peut avoir au moins deux largeurs de bande différentes qui fournissent au moins deux vitesses d'autotest ou d'étalonnage automatique différentes.
