Abstract: A charge pump generates an output voltage. A first circuit generates a pulse width-modulated signal as a function of a deviation between the output voltage and a setpoint voltage. A second circuit receives a periodic signal and conditions the supply of the periodic signal to a control input of the charge pump as a function of the state of the pulse width-modulated signal.

Abstract: An electronic device includes a carrier substrate having a front face and an electronic chip mounted on the front face. An encapsulation cover is mounted above the front face and bounds a chamber in which the chip is situated. A front opening is provided in front of an optical component of the chip. An optical element, designed to allow light to pass, is mounted on the cover in a position which covers the front opening of the cover. The optical element includes a central region designed to deviate light and a positioning pattern that is visible through the front opening. An additional mask is mounted on the encapsulation cover in a position which extends in front of the optical element. A local opening of the additional mask is situated in front of the optical component.

Abstract: A microcontroller includes distinct electronic functions and an interconnection circuit capable of transmitting in wireless fashion data between the functions. The microcontroller can be operated by writing configuration characteristics into a memory of the interconnection circuit for electronic functional circuits that do not have configuration characteristics contained in the memory and erasing configuration characteristics from the memory for electronic functional circuits that have configuration characteristics contained in the memory but are determined to not be able to wirelessly communicate with the interconnection circuit. Data can be wirelessly transmitted between the interconnection circuit and electronic functional circuits having configuration characteristics contained in the memory.

Abstract: A support substrate has first electric contacts in a front face. An electronic component is located above the front face of the support substrate and has second electric contacts facing the first electric contacts of the support substrate. An electric connection structure is interposed between corresponding first and second electric contacts of the support substrate and the electronic component, respectively. Each electric connection structure is formed by: a shim that is made of a first electrically conducting material, and a coating that is made of a second electrically conducting material (different from the first electrically conducting material). The coating surrounds the shim and is in contact with the corresponding first and second electric contacts of the support substrate and the electronic component.

Abstract: An apparatus is for testing a device to be supplied with power via USB Power Delivery (USB-PD). The apparatus includes at least one USB Type-C connector configured to be connected to the device to be supplied with power to be tested, the at least one USB Type-C connector including a power supply terminal. Processing circuitry of the apparatus is configured to verify that a voltage at the power supply terminal is lower than a first threshold, verify a role of the device, generate requests representative of power supply configurations supported by the role of the device, and verify compatibility of the power supply configurations supported by the device with standardized power supply configurations.

Abstract: A method is disclosed for operating an imaging device having a matrix of pixels arranged in rows and columns. A polarization voltage is generated on a gate of a main MOS transistor that is connected as diode. The main MOS transistor is coupled between a power supply voltage and a ground circuit. Prior to reading the pixels of a row of the matrix, a plurality of first capacitors are charged with the polarization voltage. The first capacitors are coupled between the gate of the main transistor and a ground node. Upon reading the pixels of the row, the first capacitors are discharged on respective gates of auxiliary transistors coupled between the columns and the ground node so as to switch on the auxiliary transistors and deliver a substantially identical polarization current to each column.
