Patents by Inventor Laurent Micheli

Laurent Micheli has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Protection of integrated electronic circuits from electrostatic discharge
    Patent number: 7889468
    Abstract: Circuit nodes are identified which, in unpowered mode, can be charged with positive or negative charges but cannot be discharged. Then protective elements are added to allow the discharge of these nodes. These elements do not affect the operation of the circuit in powered mode. Discharges of the two polarities are handled, positive and negative. The circuit is thus more resistant to ESD and passes CDM tests.
    Type: Grant
    Filed: January 30, 2008
    Date of Patent: February 15, 2011
    Assignee: STMicroelectronics SA
    Inventors: Philippe Galy, Laurent Micheli, Ghislain Troussier, Mickael Rien, Jean-Francois Veniant

  • Regulating device for receiving a variable voltage and delivering a constant voltage and related methods
    Patent number: 6433526
    Abstract: A regulating device for receiving a variable voltage and delivering a constant voltage includes a regulating element that includes a circuit for comparing the variable voltage with a reference voltage, a circuit for dividing the variable voltage by a factor, and a switching circuit for supplying the regulating element with a voltage equal either to the variable voltage or to the divided variable voltage. The switching circuit may be controlled by the comparison circuit in such a way that the regulating element is supplied with the variable voltage if a voltage condition is not satisfied and with the divided variable voltage if the voltage condition is satisfied.
