    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.

    Abstract: An AC/DC converter includes a first terminal and a second terminal to receive an AC voltage and a third terminal and a fourth terminal to deliver a DC voltage. A rectifying bridge is provided in the converter. A controllable switching or rectifying element has a control terminal configured to receive a control current. A first switch is coupled between a supply voltage and the control terminal to inject the control current. A second switch is coupled between the control terminal and a reference voltage to extract the control current. The first and second switches are selectively actuated by a control circuit.

    Abstract: Radiofrequency energy that is captured by a radiofrequency power harvester is stored in a storage capacitance. One or more user circuits are supplied with energy stored in the storage capacitance. The harvester operates in alternated charge and burst phases with captured radiofrequency energy stored in the storage capacitance in the charge phases and supplied to the user circuits in the burst phases to perform user circuit tasks. In response to detection of completion of the user circuit tasks in a burst phase, the harvester causes operation to shift to the next charge phase.

    Abstract: A receiver for digital signals includes a radiofrequency stage. A feedback loop controls a variable attenuation resistance applied to a modulated radiofrequency signal passing through the radiofrequency stage as a function of a comparison of an amplitude of the modulated radiofrequency signal with a reference value. A baseband stage includes an RC network cascaded to the radiofrequency stage and coupled to a baseband detector that generates the baseband signal. The feedback loop includes a circuit for detecting a range of variation of the comparison. The value of the variable resistance is controlled as a function of an end value (e.g., maximum or minimum) of the detected range of variation.

    Abstract: A power supply apparatus includes a power supply circuit and a power-on circuit. The power-on circuit detects a remotely transmitted control signal and causes a transition of the power supply circuit to a turned on state. The power-on circuit includes a transducer configured to provide a power-on signal in response to the remote control signal. The transducer triggers transition to the turned on state through a switch driven by the power-on signal output from the transducer and arranged to supply a power supply circuit enable signal. A DC blocking capacitor is connected between an output of the transducer and a control terminal of the switch.
