Abstract: A method tests at least three devices, each device including a test chain having a plurality of positions storing test data. The testing includes comparing test data in a last position of the test chain of each of the devices, and shifting test data in the test chains of each of the devices and storing a result of the comparison in a first position of the test chains of each of the devices. The comparing and the shifting and storing are repeated until all the stored test data has been compared. The at least three devices may have a same functionality and a same structure.

Abstract: A transistor includes a quasi-intrinsic region of a first conductivity type that is covered with an insulated gate. The quasi-intrinsic region extends between two first doped regions of a second conductivity type. A main electrode is provided on each of the two first doped regions. A second doped region of a second conductivity type is position in contact with the quasi-intrinsic region, but is electrically and physically separated by a distance from the two first doped regions. A control electrode is provided on the second doped region.

Abstract: A method can be used to detect the presence an object within a field of view of a time-of-flight sensor. A histogram generated by the time-of-flight sensor is obtained. The histogram includes a number of bins associating a number of detected photons to a given acquisition time. A portion of the bins of the histogram is transformed into points in a transformed domain that features a first area containing only points associated to bins representative of the presence of the object and a second area having only points associated to bins not representative of the presence of the object. The bins of the histogram representative of the presence of the object are identified from the points located in the first area.

Abstract: An artificial-neuron device includes an integration-generation circuit coupled between an input at which an input signal is received and an output at which an output signal is delivered, and a refractory circuit inhibiting the integrator circuit after the delivery of the output signal. The refractory circuit is formed by a first MOS transistor having a first conduction-terminal coupled to a supply node, a second conduction-terminal coupled to a common node, and a control-terminal coupled to the output, and a second MOS transistor having a first conduction-terminal coupled to the input, a second conduction-terminal coupled to a reference node at which a reference voltage is received, and a control-terminal coupled to the common node. A resistive-capacitive circuit is coupled between the supply node and the reference node and having a tap coupled to the common node, with the inhibition duration being dependent upon a time constant of the resistive-capacitive circuit.
