SYSTÈME D'INTERFAÇAGE D'UN CAPTEUR LC, PROCÉDÉ ASSOCIÉ ET PRODUIT DE PROGRAMME INFORMATIQUE

摘要

A system for interfacing an LC sensor (10) is described. The system comprises means (206) configured to selectively start an oscillation of the LC sensor (10). The system comprises also an analog peak detector (280) configured to determine a signal ( V peak ) being indicative of a peak voltage of the oscillation of the LC sensor (10) and detection means (208, 230) configured to determine the state of the LC sensor (10) as a function of the signal ( V peak ) determined by the analog peak detector (280).
