Abstract: In accordance with an embodiment, a linear voltage regulator includes: a first transistor coupled between a first input terminal and an output terminal, the first input terminal adapted to receive a first voltage, and the output terminal adapted to provide a regulated voltage; a second transistor coupled between a second input terminal and the output terminal, the second input terminal adapted to receive a second voltage; and an amplifier of a difference between a third voltage proportional to the voltage at the output terminal and a reference voltage, an output of said amplifier being selectively coupled to a control terminal of the first transistor and to a control terminal of the second transistor, the amplifier being supplied by a fourth voltage corresponding to a highest voltage of the first voltage and the second voltage.

Abstract: 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.
