Abstract: An embodiment method for modifying the frequency of a clock signal clocking an integrated circuit supplied by a voltage controller comprises, in response to a command for the modification, varying the frequency of the clock signal at a rate allowing a supply voltage to be controlled by the controller. The variation comprises at least one series of successive divisions of the frequency of the clock signal into successive intermediate signals of respective intermediate frequencies.

Abstract: An optical sensor includes pixels. Each pixel has a photodetector. A readout circuit performs a process over an exposure time where the photodetector is connected to a reverse bias voltage supply to reset a voltage across the photodetector, and the photodetector is disconnected from the reverse bias voltage supply until that the voltage across the photodetector decreases in response to received ambient light. An ambient light level is then determine an based on a number of times the voltage across the photodetector is reset over the exposure time.

Abstract: In accordance with an embodiment, a method verifies contents of a plurality of registers having two first registers, where each of the plurality of registers is configured to store a data word and a verification bit. The method includes determining whether a value of the verification bit of each respective register of the plurality of registers corresponds to the data word of its respective register. The data words stored in the two first registers are selected so that the bits of a same rank of the two first registers include two complementary bits, each bit of a common binary word is associated with a respective register of the plurality of registers, and the value of the verification bit of each respective register depends on the data word of the respective register and the bit of the common binary word associated with the respective register.

Abstract: A method of measuring the phase of a response signal relative to a periodic excitation signal, comprises the steps of producing for each cycle of the response signal two transitions synchronized to a clock and framing a reference point of the cycle; swapping the two transitions to confront them in turns to the cycles of the response signal; measuring the offsets of the confronted transitions relative to the respective reference points of the cycles; performing a delta-sigma modulation of the swapping rate of the two transitions based on the successive offsets; and producing a phase measurement based on the duty cycle of the swapping rate.

Abstract: An integrated circuit includes a solder pad which includes, in a superposition of metallization levels, an underlying structure formed by a network of first regular metal tracks that are arranged for reinforcing the mechanical strength of the underlying structure and electrically connecting between an upper metallization level and a lower metallization level of the underlying structure. The underlying structure further includes a detection electrical path formed by second metal tracks passing between the first metal tracks in the metallization levels, the detection electrical path having an input terminal and an output terminal. Electrical sensing of the detection electrical path is made to supply a measurement which is indicative of the presence of cracks in the underlying structure.

Abstract: A measurement of the rotation speed of an object is made using a time-of-flight sensor configured to detect a passing of one or more of elements of the object through a given position. The time-of-flight sensor is further mounted on a one-person vehicle configured to protect the one-person vehicle against collisions through the making a time-of-flight measurement of a relative speed between the one-person vehicle and an obstacle.

Abstract: A voltage source device includes a voltage converter configured to generate a supply voltage at an output node of the voltage converter. A current source is configured to apply a current to a first output terminal of the voltage source device in order to detect a cable voltage drop. A compensation circuit is configured to generate a feedback signal based on a voltage at the first output terminal. The supply voltage is generated based on the feedback signal.
