Abstract: A datum is written to a memory, by splitting a binary word, representative of the datum and an error correcting or detecting code, into a first part and a second part. The first part is written at a logical address in a first memory circuit. The second part is written at the logical address in a second memory circuit. The error correcting or detecting code is dependent on both the datum and the logical address.

Abstract: Authenticating a device using processing circuitry that generates fingerprints based on states of a plurality of nodes that are coupled to a plurality of circuits. A first fingerprint is generated at a first time based on first states of the plurality of nodes. A second fingerprint is generated at a second time based on second states of the plurality of nodes, the first fingerprint influencing the second states. Electronic data is obtained from the device to be authenticated. The electronic data is compared with a fingerprint generated and a determination whether to authorize operation of the device is made based on a result of the comparison.

Abstract: An acquisition stage receives a digital input signal and generates therefrom a first digital signal and a second digital signal complementary thereto. First and second processing stages receive the first and second digital signals and generate therefrom first and second analog signals in time with first and second complementary clock signals. An output stage generates an internal clock signal equivalent to one of: the first clock signal phase shifted by a duration of a transient occurring during a period of the first clock signal, or the second clock signal phase shifted by a duration of a transient occurring during a period of the second clock signal. The output stage produces an analog output signal equal to the first analog signal when the internal clock signal is at a first logic level, and equal to the second analog signal when the internal clock signal is at a second logic level.

Abstract: An N-bit type charge redistribution analog-to-digital conversion device includes an input terminal configured to receive an input signal and coupled via a line to an output terminal. The output terminal is configured to be coupled to a comparator. The device further includes three reference potential sources of different values and a network of capacitors, where a first terminal of each capacitor is coupled to the line, and where a second terminal of each capacitor is coupled to switching circuit configured for coupling the second terminal of each capacitor to one of the reference potentials.

Abstract: A method for transmitting and/or receiving a potential aggressor audio signal includes a transmission and/or a reception of successive groups of data timed by a first clock signal within respective successive frames synchronized by a second clock signal. In the presence of a risk of interference of the potential aggressor audio signal with a different, potential victim, signal, during the transmission or reception of the potential aggressor audio signal, the frequency of the first clock signal is modified while keeping the frequency of the second clock signal unchanged.

Abstract: In one embodiment, a waveguide includes an upstream portion, a downstream portion, and an intermediate portion between the upstream portion and the downstream portion. A first band is disposed on an insulating layer, the first band oriented along a first direction. A first lateral strip and a second lateral strip are disposed on either side of the first band, the first lateral strip and the second lateral strip being thinner or interrupted along the intermediate portion.

Abstract: A circuit for controlling a first plurality of transistors connected in parallel and a second plurality of transistors connected in parallel, includes: a first plurality of stages, a respective one of the first plurality of stages being configured to supply a first control signal to a respective one of the first plurality of transistors; and a second plurality of stages, a respective one of the second plurality of stages being configured to supply a second control signal to a respective one of the second plurality of transistors. An output current of the respective one of the first plurality of stages is regulated based on a difference between a first value representative of a sum of output currents of each stage of the first plurality of stages and a second value representative of a sum of set points assigned to the first plurality of stages.
