Abstract: An ambient light sensor includes pixels arranged in an array. Each pixel includes a doped insulated well of a first type, a pinned photodiode in the well, a doped region of a second type arranged in the well, a transfer gate coupling the photodiode to said region, and a first circuit applying a first or second potential to the well. A successive approximation analog-to-digital converter of the sensor has a node connected to the doped regions of the pixels, a switch applying a third potential to the node, a comparator coupled to the node, and a second circuit receiving an output of the comparator and controlling the first circuits to selectively apply the first and second potentials. A sensor control circuit controls the gates and the first switch.

Abstract: A first terminal receives a first DC voltage. A switch selectively couples the first terminal to a second terminal providing an output. A control circuit selectively actuates the switch in response to a comparison of the first DC voltage to a second DC voltage. A low-dropout (LDO) linear voltage regulator, connected between the first and third terminals, operates to provide the second DC voltage from the first DC voltage.

Abstract: A device includes a printed circuit board substrate, an antenna connected to the printed circuit board substrate, an amplifier connected to the printed circuit board substrate, and a matching track having a first end electrically connected to an input of the amplifier and a second end electrically connected to an output of the antenna. The matching track has an outgrowth that is symmetrical along a median axis of the outgrowth. The matching track is rectilinear and has a constant width over an initial part extending between the widening area and the first end. A median axis of the initial part and the median axis of the outgrowth form an angle comprised between 60 and 120°.
