Patents by Inventor Michael Joehren

Michael Joehren 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).

  • Patent number: 8159032
    Abstract: The electronic device comprises an ESD device (20) for protection against electrostatic discharge and provided with suitable protection elements (22) in combination with an integrated circuit (10). The integrated circuit (10) is particularly a so-called bridging circuit or driver circuit for external devices such as SIM cards, memory sticks, USB busses or 12C busses. The ESD device (20) is provided with a chip scale package in that the bumps (40) can be placed on a printed circuit board directly. The integrated circuit (10) is stacked on the ESD device (20).

  • Publication number: 20110198725
    Abstract: The present invention relates to an electric component comprising at least one first MIM capacitor having a ferroelectric insulator with a dielectric constant of at least 100 between a first capacitor electrode of a first electrode material and a second capacitor electrode of a second electrode material. The first and second electrode materials are selected such that the first MIM capacitor exhibits, as a function of a DC voltage applicable between the first and second electrodes, an asymmetric capacity hysteresis that lets the first MIM capacitor, in absence of the DC voltage, assume one of at least two possible distinct capacitance values, in dependence on a polarity of a switching voltage last applied to the capacitor, the switching voltage having an amount larger than a threshold-voltage amount. The invention is applicable for ESD sensors, memories and high-frequency devices.

  • Patent number: 7952460
    Abstract: An electronic circuit has an inductor. The inductor comprises a first number of electrically conductive tracks (108, . . . ) in, or on, a substrate (105). The tracks are separated from one another. The inductor comprises a second number of electrically conductive wires (120, . . . ). The ends of each wire contacts two different ones of the tracks. Among the first number of tracks there is at least a specific track that is electrically isolated from the wires upon the wires having been connected. Such an inductor can be made using a standardized track configuration on a substrate, and selectively skipping one or more tracks in order to determine the inductance.
