Systems, devices and methods are provided to switch between transmit and receive modes in wireless hearing aids. One aspect relates to an apparatus for use within a communication system that has an inductive coil connected to a tuning capacitor at a node. An amplifier is connected to the node through a DC blocking capacitor to receive an induced signal in the inductive coil in a receive mode. A driver energizes the inductive coil with a driven signal in a transmit mode. According to various embodiments, the apparatus transforms the inductive coil, the tuning capacitor and the DC blocking capacitor into an equivalent series resonant circuit to reduce an inductive load in the transmit mode, and transforms the inductive coil, the tuning capacitor and the DC blocking capacitor into an equivalent parallel resonant circuit to increase an inductive load in the receive mode.

Cette invention concerne des systèmes, des dispositifs et des procédés permettant de passer du mode émission au mode réception et inversement dans des prothèses auditives sans fil. Un aspect de cette invention concerne un appareil destiné à être utilisé dans un système de communication qui comprend une bobine inductive connectée à un condensateur d'accord au niveau d'un noeud. Un amplificateur est connecté au noeud au moyen d'un condensateur de blocage CC afin de recevoir un signal induit dans la bobine inductive en mode réception. Un excitateur est chargé d'exciter la bobine inductive avec un signal excité en mode émission. Selon divers modes de réalisation, l'appareil transforme la bobine inductive, le condensateur d'accord et le condensateur de blocage CC en un circuit résonant série équivalent afin que la charge inductive soit réduite en mode émission, et transforme la bobine inductive, le condensateur d'accord et le condensateur de blocage CC en un circuit résonant parallèle équivalent afin que la charge inductive soit augmentée en mode réception.
