Patents by Inventor Cristi Stefan Zegheru

Cristi Stefan Zegheru 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).

  • Multi-load drive circuit
    Patent number: 10026574
    Abstract: A circuit arrangement includes a first number of loads connected in series. Each of a second number of drive units is coupled to at least one of the first number of loads, and is configured to assume a first operation state or a second operation state. A current source circuit is coupled in series with the first number of loads and is configured to control a load current.
    Type: Grant

    Date of Patent: July 17, 2018
    Assignee: Infineon Technologies AG
    Inventors: Michael Lenz, Rolf-Peter Goeser, Cristi-Stefan Zegheru

  • Ultra low current consumption comparator for thermal shutdown
    Patent number: 8197127
    Abstract: An embodiment of the invention relates to a temperature-sensing device and a related method. In an embodiment, the device senses a temperature with a first sensing circuit configured to assert a signal when temperature is above a first temperature threshold level, and a second sensing circuit configured to substantially disable a bias current that powers the first sensing circuit when a sensed level of temperature is below a second, lower temperature threshold level. Accordingly, the device is able to draw substantially reduced current from a power source when the sensed temperature level is less than the second threshold level. Other physical parameters such as strain or pressure may also be sensed using the same technique.
