Abstract: An RF transmitter comprises a capacitive energy storage, an output stage and a switching circuit with an open state and a closed state. The capacitive energy storage forms with the antenna when connected thereto a resonance circuit with a resonance frequency and a quality factor. The output stage provides an electric transmission signal to the resonance circuit. The switching circuit comprises a first transistor for switching between the open state and the closed state and is connected to an antenna output terminal through a capacitance formed by the capacitive energy storage such that the maximum signal voltage occurring across the switching circuit in its open state is lower than the maximum signal voltage occurring across the antenna output terminals. The transmitter is adapted to alter the quality factor by changing the series resistance of the switching circuit in its closed state.

Abstract: A receiving antenna circuit is arranged in a reactive near-field of a modulated magnetic induction signal and forms a narrow band-pass filter. The output of the antenna circuit is not subjected to any frequency translation prior to digitizing, and the signal may nevertheless be digitized with low resolution, which radically reduces the power consumption of the receiving circuits. The reduction in power consumption is of several orders of magnitude, which allows implementation of such receiving circuits in battery-driven devices such as hearing devices without substantially affecting the battery life.

Abstract: A synthetic-frequency RF transmitter is provided for transmitting an electromagnetic signal via an electrically short antenna. The transmitter comprises a reactive energy storage with an effective reactance adapted to form with the antenna a resonance circuit with a resonance frequency and a driver adapted to provide to the resonance circuit an electric transmission signal having an instantaneous frequency that varies in dependence on an information signal. The transmitter is characterized in that the transmitter is adapted to dynamically change the resonance frequency by changing the effective reactance in dependence on the information signal. Thus, the instantaneous pass-band of the resonance circuit may be controlled to substantially always comprise the instantaneous frequency of the electric transmission signal and thus of the electromagnetic signal.
