    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.

    Abstract: A low dropout voltage regulator unit includes an error amplifier and a power stage having an output terminal that is looped back onto the error amplifier and is capable of delivering an output current to a load. The unit includes multiple main supply inputs that are intended to potentially receive, respectively, multiple different supply voltages. The power stage includes multiple power paths that are connected, respectively, between the main supply inputs and the output terminal, are individually selectable and each comprise an output transistor. The unit also includes a selector circuit connected to the main supply inputs and configured to select one of the power paths according to a selection criterion. The error amplifier includes an output stage configured to selectively control the output transistor of the selected power path.

    Abstract: A circuit includes an amplifier having a first power terminal configured to be coupled to a supply voltage and a second power terminal configured to be coupled to a reference potential. The circuit further includes a first impedance element coupled between a first input terminal of the amplifier and a first output terminal of the amplifier. The circuit additionally includes a second impedance element coupled between the first input terminal and the reference potential. The amplifier is configured to output a first voltage at a second output terminal of the amplifier in response to the supply voltage being greater than an output voltage at the first output terminal of the amplifier. The amplifier is further configured to output a second voltage at the second output terminal of the amplifier in response to the supply voltage being less than the output voltage at the first output terminal of the amplifier.

    Abstract: A circuit includes, in series between a first terminal and a second terminal of application of a power supply voltage, and first and second branches. The first branch includes a first transistor and a first current source coupled to the first transistor. The second branch includes a resistive element, a second transistor coupled to the resistive element and forming a current mirror with the first transistor and a second current source coupled to the second transistor. The resistive element conditions a threshold of detection of a variation of the power supply voltage.
