Abstract
A power receiver includes a resonant circuit generating an internal supply voltage. A voltage rectification circuit receives the internal supply voltage and generate a corresponding rectified voltage. A voltage regulator receives the rectified voltage and a modulation signal and is configured to generate a corresponding regulated voltage. A controlled voltage-to-current converter receives the regulated voltage and the modulation signal. The converter operates to deliver, through an output line of the power receiver, an output current having a DC value corresponding to the DC value of said regulated voltage and having an AC value corresponding to said modulation signal.
