Raghu Sreeramaneni 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: 11942167
    Abstract: Systems, methods, and apparatuses relating to interlocking transistor active regions are disclosed. An apparatus includes a gate including electrically conductive material and an active material including a doped semiconductor material. A portion of the active material overlapped by the gate has an at least substantially triangular shape. An apparatus includes a plurality of active materials. Each active material includes tapered ends and a plurality of gates. The plurality of active materials is arranged in an interlocking pattern with at least some tapered ends of the active materials interlocking with at least some others of the tapered ends. The plurality of gates overlaps the interlocked tapered ends of the plurality of active materials.
    Type: Grant
    Filed: February 24, 2020
    Date of Patent: March 26, 2024

  • Patent number: 7982494
    Abstract: Embodiments of the present invention include systems for calibrating an output circuit. A comparator is coupled to a calibration terminal and configured to determine whether the calibration terminal is in a first state coupled to a calibration resistor or in a second state. A calibration circuit is coupled to the calibration terminal and configured to generate a calibration value based in part on the presence or absence of the calibration resistor. An impedance selector is coupled to the calibration circuit, the comparator, and a default calibration value. The impedance selector is configured to select the default calibration value when the comparator indicates the calibration terminal is in the second state and to select the calibration value coupled from the calibration circuit when the comparator indicates the calibration terminal is in the first state.
