Abstract: An optical emitting circuit includes an array of M optical sources distributed in N groups, where N is lower than M. A controller is configured to generate N periodic square wave control signals that are successively mutually phase shifted by pi/N and that all have the same period, and to cyclically activate/deactivate all the optical sources of the N groups using the control signals. The optical emitting circuit is configured so that each group is activated when a corresponding control signal is in its first state and deactivated when the corresponding control signal is in its second state. The number of optical sources in each group and the order of the groups in the sequence of activations/deactivations are chosen so as to generate an optical signal having an amplitude that sinusoidally varies in steps.

Abstract: A first resistor and a second resistor are coupled in series between a voltage source and an active load. When the current drawn by the active load exceeds a current threshold corresponding to a maximum admissible voltage drop across the first resistor, a stabilization current is delivered to the node common to the series coupled first and second resistors in such a way as to stabilize the voltage on the terminals of the active load at a threshold value. In the presence of such a current in excess of the current threshold, the current consumed by the active load is measured from the voltage drop across the second resistor. Conversely, if the current is less than the current threshold, the current consumed by the active load is measured from the voltage drop across the first resistor.

Abstract: A method and apparatus for detecting a critical duty cycle that maximizes an output power of a boost converter is provided. In the method and apparatus, the boost converter may be operated at or below the critical duty cycle. In the method and apparatus, a first voltage that is a function of an output voltage of a boost converter and voltage drops across a first set of parasitic resistances of the boost converter is detected. A second voltage that is a function voltage drops across a second set of parasitic resistances of the boost converter is also detected. The voltages are compared to determine the critical duty cycle and the boost converter is operated in accordance with a duty cycle that does not exceed the critical duty cycle.

Abstract: An electronic device includes a support plate having a mounting face and an electrical connection network. An integrated circuit chip is mounted on the mounting face and linked to the electrical connection network. An en encapsulation block embeds the integrated circuit chip. An additional element made of an electrically conductive material is at least partly embedded within the encapsulation block. The additional conductive element has a main portion extending parallel to the support plate and has a secondary portion that is linked electrically to the integrated circuit chip. An opening is formed in the encapsulation block, and the secondary portion extends into that opening to make the electrical link. The additional conductive element may be an antenna.

Abstract: An audio device includes an audio amplifier configured to receive an input signal and generate a differential output signal. A first signal combiner circuit is configured to generate a time-convolution signal of an analog current signal and an analog voltage signal. The analog current signal corresponds to a current at the differential output signal, and the analog voltage signal corresponds to a voltage across the differential output signal. A second signal combiner circuit is configured to subtract the generated time-convolution signal from the input signal.
