    Abstract: An integrated optoelectronic or optical device is formed by a polarization-splitting grating coupler including two optical waveguides, a common optical coupler and flared optical transitions between the optical coupler and the optical waveguides. The optical coupler is configured for supporting input/output of optical waves. A first region of the optical coupler lies at a distance from the flared optical transitions. The first region includes a first recessed pattern. Second regions of the optical coupler lie between the first region and the flared optical transitions, respectively, in an adjoining relationship. The second regions include a second recessed pattern different from the first recessed pattern.

    Abstract: A low-dropout regulator includes a power stage having an output terminal coupled to a load circuit operable in different operating modes in which it receives different output currents. An error amplifier has a first input coupled to a reference voltage and an output coupled to an input terminal of the power stage. A compensation circuit includes a first stage with an RC filter coupled to the input terminal of the power stage, and generating an initial compensation voltage. A second stage includes a first transistor coupled between a supply voltage and a second node, and controlled by a complementary control signal, a high-side capacitor coupled between the second node and ground, and a third transistor coupled between the initial compensation voltage and the second node, and controlled by a control signal representative of the current operating mode of the load circuit.

    Abstract: An electronic device includes a module that delivers a positive temperature coefficient output voltage at an output terminal. A thermistor includes a first MOS transistor operating in weak inversion mode and having a negative temperature coefficient drain-source resistance and whose source is coupled to the output terminal. A current source coupled to the output terminal operates to impose the drain-source current of the first transistor.
