Abstract
In an embodiment an electronic device includes a first electronic circuit having a capacitive element with a variable capacitance, wherein the first electronic circuit is configured to couple the capacitive element to an antenna, to measure, by successive iterations, a first analog signal representative of a variation of an instantaneous electric power received by the antenna or representative of the instantaneous electric power received by the antenna and to modify the capacitance of the capacitive element until an amplitude of the instantaneous electric power received by the antenna is a maximum, wherein the antenna is configured to capture an amplitude-modulated electromagnetic field.
