  • Publication number: 20130088897
    Abstract: An integrated circuit controls a switch of a switching current regulator. The current regulator comprises primary and secondary windings where a first and a second current flow, respectively. The switch is adapted to initiate or interrupt the circulation of the first current in the primary winding. The control integrated circuit comprises a comparator configured to compare a first signal representative of said first current to a second signal and a divider circuit configured to generate said second signal as a ratio of a third signal, proportional to a voltage on the primary winding, with a voltage on a capacitor. The capacitor is charged by a further current controlled by the third signal when the second current is different from zero. The capacitor is discharged through a parallel-connected resistor when the value of said second current is substantially zero.

  • Publication number: 20130088272
    Abstract: The present disclosure relates to a low consumption flip-flop circuit with data retention, comprising at least one flip-flop and at least one retention cell connected to the output of the flip-flop and configured so that during normal operation of the flip-flop circuit, the retention cell transmits the data or logic state present on the output terminal of the flip-flop to its own output terminal, while during low consumption operation of the flip-flop circuit a latch circuit of the retention cell suitable to memorize data or a logic state corresponding to the last data or logic state present on the output terminal of the flip-flop is activated.

  • Publication number: 20130083490
    Abstract: An electronic board includes conducting traces having an upper surface at least partially sunken with respect to a gluing surface of the board. A surface mount technology electronic device for mounting to the board includes insulating windows that define gluing sites within one or more pins. An electronic system is formed by one or more of such surface mount technology electronic devices mounted to electronic board. The devices are attached using a wave soldering technique that flows through channels formed by the sunken conductive traces.

  • Publication number: 20130083489
    Abstract: An electronic system includes an insulating structural element with a coupling surface configured for coupling the electronic system with at least one further electronic system. The electronic system further includes at least one conducting contact element at least partially exposed on the coupling surface. Each conducting contact element has a soldering surface supporting reflow soldering of the conducting contact element with a corresponding further contact element of the further electronic system. In addition, each conducting contact element has at least one lateral surface protruding from the insulating structural element. The soldering surface of the conducting contact element includes at least one channel having an opened end at the protruding lateral surface, the channel configured to facilitate dispersion of waste gas produced during reflow soldering.

  • Publication number: 20130082258
    Abstract: A method for testing a strip of MEMS devices, the MEMS devices including at least a respective die of semiconductor material coupled to an internal surface of a common substrate and covered by a protection material; the method envisages: detecting electrical values generated by the MEMS devices in response to at least a testing stimulus; and, before the step of detecting, at least partially separating contiguous MEMS devices in the strip. The step of separating includes defining a separation trench between the contiguous MEMS devices, the separation trench extending through the whole thickness of the protection material and through a surface portion of the substrate, starting from the internal surface of the substrate.

  • Publication number: 20130031950
    Abstract: A microelectromechanical gyroscope having a supporting structure; a mass capacitively coupled to the supporting structure and movable with a first degree of freedom and a second degree of freedom, in response to rotations of the supporting structure about an axis; driving components, for keeping the mass in oscillation according to the first degree of freedom; a read interface for detecting transduction signals indicating the capacitive coupling between the mass and the supporting structure; and capacitive compensation modules for modifying the capacitive coupling between the mass and the supporting structure. Calibration components detect systematic errors from the transduction signals and modify the capacitive compensation modules as a function of the transduction signals so as to attenuate the systematic errors.

  • Publication number: 20130033274
    Abstract: A microelectromechanical sensor includes a supporting structure and a sensing mass, which is elastically coupled to the supporting structure, is movable with respect thereto with one degree of freedom in response to movements according to an axis and is coupled to the supporting structure through a capacitive coupling. A sensing device senses, on terminals of the capacitive coupling, transduction signals indicative of displacements of the first sensing mass according to the degree of freedom. The sensing device includes at least one first reading chain, having first operative parameters, one second reading chain, having second operative parameters different from the first operative parameters, and one selective electrical connection structure that couples the first reading chain and the second reading chain to the first terminals.
