Abstract: A device of contactless communication by active load modulation includes a receive circuit configured to receive as an input a reception signal originating from a magnetic field intended to be received by an antenna. A transmit circuit has an output coupled to the antenna with a modulation signal in phase with the reception signal intended to be delivered thereon. A circuit compensates for a delay of the modulation signal due to the transmit circuit and to the amplitude of the reception signal. The compensation circuit determines a phase-shift value to be applied to an input signal of the transmit circuit to compensate for the delay.

Abstract: The present disclosure provides a circuit for supplying a clock signal. An example circuit for supplying a clock signal comprises a selector of one signal out of a plurality of clock signals; a switch between the selector and a node for outputting the selected clock signal, the circuit being configured so that the application of a control signal for selecting one of the clock signals causes, in the order, the turning off of the switch, the selection of the signal via the selector, and the turning on of the switch.

Abstract: The present description concerns a correction circuit for a bandgap circuit comprising a first bipolar transistor and a second bipolar transistor, the bandgap circuit being configured to deliver a temperature-stable DC voltage based on the first and second bipolar transistors, the correction circuit being configured to generate a correction current equal to a difference in the base currents of said first and second transistors, and inject the correction current on the emitter of one of said first and second bipolar transistors to correct an error on the temperature-stable voltage resulting from a current gain difference between said first and second bipolar transistors.

Abstract: A MEMS metamaterial has a substrate and a suspended structure having an elementary cell which extends at a distance from the substrate along a first direction. The elementary cell has a first structural region having a first material with a first coefficient of thermal expansion. The first structural region has a first side facing the substrate and a second side opposite to the first side. The elementary cell also has a second structural region having a second material different from the first material and with a second coefficient of thermal expansion different from the first coefficient of thermal expansion. The second structural region extends on at least part of the first structural region, on the first side, the second side, or both the first and second side of the first structural region.

Abstract: A method of operating a touch screen panel includes initiating a communication between the panel and an active pen and determining a touch zone of the panel. The touch zone includes communication channels that are operating by touch while bi-directional communication is occurring between the panel and active pen. Communications channels within the touch zone are disabled and communication between the panel and the active pen can occur while the communications channels within the touch zone are disabled. When it is determined that the communication between the panel and the active pen has stopped, communications channels continue to be disabled within the touch zone for a set time delay while no communication occurs between the panel and the active pen. After the set delay time, the communication channels within the touch zone are enabled.

Abstract: A memory cell including a set of active regions that overlay a set of gate regions to form a pair of cross-coupled inverters. A first active region extends along a first axis. A first gate region extends transversely to the first active region and overlays the first active region to form a first transistor of the pair of cross-coupled inverters. A second gate region extends transversely to the first active region and overlays the first active region to form a second transistor of the pair of cross-coupled inverters. A second active region extends along a second axis and overlays the first gate region to form a third transistor of the pair of cross-coupled inverters. A fourth active region extending along a third axis and overlays a gate region to form a transistor of a read port.

Abstract: A non-volatile memory includes a row decoder comprising, for each word-line, a respective pull-up connected to a first supply voltage and a switching circuit for selectively connecting one of the word-lines to ground. The row decoder comprises a demultiplexer connected to a second supply voltage smaller than the first, and configured to assert an enable signal as a function of an address signal. The switching circuit comprises two n-channel FETs connected in series between the word-line and ground, with the gate terminal of one FET connected to a first signal and the gate terminal of the other FET connected to a second voltage. A bias circuit is configured to set the voltage between the two FETs to the second voltage when the FETs are opened. The switching circuit comprises a p-channel FET connected between the word-line and the second voltage, and a gate terminal connected to a second signal.
