A reader is adapted to wirelessly exchanging information with a wireless apparatus. The reader includes a signal generator configured to generate a modulation signal. An emitter/receptor stage is configured to be driven by the modulation signal. A switched-mode power supply is configured to power the emitter/receptor stage. The switched-mode power supply includes a power switch controlled in function of the modulation signal.

The present description describes an image sensor including an array of pixels arranged inside and on top of a region of a semiconductor substrate electrically insulated from the rest of the substrate by insulating trenches crossing the substrate, each pixel including a photoconversion area and at least two assemblies, each including a memory area and a transfer gate coupling the memory area to the photoconversion area, and a circuit configured to apply, for each pixel and at least during each integration phase, a bias voltage different from ground to a portion of the substrate having the pixel arranged inside and on top of it.

A switched-mode power converter device includes an inductive element coupling a first node receiving an input voltage to a second node. A first transistor couples the second node to a third node generating an output voltage. A control circuit includes a first switch coupling the third node to a control terminal of the first transistor.
