Title
(EN) TRANSIENT VOLTAGE SUPPRESSION CIRCUIT FOR AN IMPLANTED RFID CHIP
(FR) CIRCUIT DE SUPPRESSION DE TENSION TRANSITOIRE POUR UNE PUCE RFID IMPLANTÉE
Abstract
(EN)
A transient voltage suppressing (TVS) circuit includes an implantable RFID chip, an antenna associated with the RFID chip, and a transient voltage suppressor electrically connected in parallel to both the RFID chip and the antenna. The transient voltage suppressor may be formed of an array of diodes, such as back-to-back diodes, at least one Zener diode, or back-to-back or series opposing Zener diodes. In preferred embodiments, the antenna is formed of a biocompatible material suitable for long-term exposure to body tissue and body fluids, and the RFID chip and the transient voltage suppressor are disposed within a hermetically sealed biocompatible container.
(FR)
L'invention porte sur un circuit de suppression de tension transitoire (TVS) qui comprend une puce RFID implantable, une antenne associée à la puce RFID et un suppresseur de tension transitoire électriquement connecté en parallèle à la fois à la puce RFID et à l'antenne. Le suppresseur de tension transitoire peut être formé d'un réseau de diodes, telles que des diodes en opposition, au moins une diode Zener ou des diodes Zener en opposition ou opposées en série. Dans des modes de réalisation particuliers, l'antenne est formée d'un matériau biocompatible approprié pour une exposition à long terme à un tissu de corps et des fluides corporels, et la puce RFID et le suppresseur de tension transitoire sont disposés dans un contenant biocompatible hermétiquement scellé.
