Abstract: A device for converting radio-frequency energy into DC current, receiving at least one radio-frequency signal at input and generating at output a DC current capable of powering at least one load. The device has at least two conversion stages, each including: a radio-frequency filtering module, connected to a first input node of the conversion stage, configured to filter the radio-frequency signal; a voltage shift module, connected between a second input node of the conversion stage, the radio-frequency filtering module and an intermediate node of the conversion stage, configured to shift a voltage present at the first input node to the intermediate node; a voltage rectifier module, connected between the intermediate note, the second input node and an output node of the conversion stage, configured to rectify the voltage of the intermediate node and deliver a rectified voltage on the output node.
