    Abstract: A capacitor has a variable capacitance settable by a bias voltage. A method for setting the bias voltage including the steps of: (a) injecting a constant current to bias the capacitor; (b) measuring the capacitor voltage at the end of a time interval; (c) calculating the capacitance value obtained at the end of the time interval; (d) comparing this value with a desired value; and (e) repeating steps (a) to (d) so as long as the calculated value is different from the set point value. When calculated value matches the set point value; the measured capacitor voltage is stored as a bias voltage to be applied to the capacitor for setting the variable capacitance.

    Abstract: A triac has a vertical structure formed from a silicon substrate having an upper surface side. A main metallization on the upper surface side has a first portion resting on a first region of a first conductivity type formed in a layer of a second conductivity type. A second portion of the main metallization rests on a portion of the layer. A gate metallization on the upper surface side rests on a second region of the first conductivity type formed in the layer in the vicinity of the first region. A porous silicon bar formed in the layer at the upper surface side has a first end in contact with the gate metallization and a second end in contact with the main metallization.

    Abstract: A rectifying circuit including: between a first terminal of application of an AC voltage and a first rectified voltage delivery terminal, at least one first diode; and between a second terminal of application of the AC voltage and a second rectified voltage delivery terminal, at least one first anode-gate thyristor, the anode of the first thyristor being connected to the second rectified voltage delivery terminal; and at least one first stage for controlling the first thyristor, including: a first transistor coupling the thyristor gate to a terminal of delivery of a potential which is negative with respect to the potential of the second rectified voltage delivery terminal; and a second transistor connecting a control terminal of the first transistor to a terminal for delivering a potential which is positive with respect to the potential of the second rectified voltage delivery terminal, the anode of the first thyristor being connected to the common potential of voltages defined by said positive and negative potentials.

    Abstract: A vertical power component includes a doped silicon substrate of a first conductivity type. A local well of a second conductivity type extends from an upper surface of the substrate. A passivation structure coats a peripheral region of the upper surface side of the substrate surrounding the well. This passivation structure includes, on top of and in contact with the peripheral substrate region, a first region made of a first passivation material and a second region made of a second passivation material. The second region generates, in a surface region of the substrate in contact with said second region, a local increase of the concentration of majority carriers in the substrate.
