Patents by Inventor Luca Petruzzi

Luca Petruzzi 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: 7911260
    Abstract: Circuit, system and method of current control circuits are disclosed. In one embodiment, a control circuit includes a first MOS transistor and a second MOS transistor. The first source/drains of the first and the second MOS transistors are coupled to an output of a power source. A second source/drain of the first MOS transistor is coupled to a first output node of the current control circuit. A second source/drain of the second MOS transistor is coupled to a second output node of the current control circuit. The control circuit further includes a means to block flow of current from the first output node of the current control circuit to the second output node of the current control circuit.
    Type: Grant

  • Patent number: 7621671
    Abstract: Some embodiments discussed relate to an apparatus comprising a temperature sensor disposed in an integrated circuit, the temperature sensor including a bipolar transistor having a collector coupled to a portion of a substrate of the integrated circuit, and a bandgap reference circuit configured to generate a reference voltage, and a comparator coupled to the temperature sensor and the bandgap reference circuit, the comparator configured to receive a first voltage from the emitter of the bipolar transistor and the reference voltage from the bandgap reference circuit and generate a switch-off signal based on a voltage difference between the first voltage and the reference voltage.
