Abstract:
A device, e.g., a hearing aid, has an electronic circuit for wireless communication of a digital signal. The circuit has a driver driving an RLC tank. The driver has a plurality of inverters whose outputs are coupled to a node of the coil via a respective one of multiple capacitors in the tank. The circuit has a controller that selectively drives one or more of the inverters with the digital signal and connects the inputs of the other inverters to a supply voltage or ground. The tank has a further plurality of series arrangements of a further capacitor and a high-voltage switch connected between the node and ground. The controller is configured for controlling the high-voltage switches.
