More Information
Summary:A local oscillator frequency-based proximity sensor is disclosed. The proximity sensor includes: an integrated circuit having at least a capacitive element; and an antenna designed with an inductive element; wherein the capacitive element and the inductive element form a proximity sensor oscillating at a local oscillator (LO) frequency, wherein the integrated circuit is configured to measure a frequency offset from the LO frequency, wherein the frequency offset is indicative of a detection of a nearby object. L'invention concerne un capteur de proximité basé sur la fréquence d'oscillateur local. Le capteur de proximité comprend : un circuit intégré ayant au moins un élément capacitif; et une antenne conçue avec un élément inductif; l'élément capacitif et l'élément inductif forment un capteur de proximité oscillant au niveau d'une fréquence d'oscillateur local (LO), le circuit intégré étant configuré pour mesurer un décalage de fréquence pa rapport à la fréquence LO, le décalage de fréquence étant indicatif d'une détection d'un objet proche.
