Abstract
A near-field communication device includes an oscillating circuit, a rectifying bridge configured to rectify a voltage across the oscillating circuit, and a voltage-controlled oscillator configured to supply a reference frequency. The voltage-controlled oscillator is powered and controlled by a voltage that is a function of an output voltage of the rectifying bridge.
