  • Patent number: 11893185
    Abstract: Systems, methods, and devices are described that may mitigate pixel and touch crosstalk noise. A touch processing system may compensate touch scan data to reduce the noise based on a luminance value. An image processing system may determine the luminance value based on image data and a display brightness value of an electronic display. Using the compensated touch scan data, the touch processing system may determine a proximity of a capacitive object to at least one touch sense region of the electronic display.

  • Publication number: 20230223406
    Abstract: Non-planar semiconductor devices having doped sub-fin regions and methods of fabricating non-planar semiconductor devices having doped sub-fin regions are described. For example, a method of fabricating a semiconductor structure involves forming a plurality of semiconductor fins above a semiconductor substrate. A solid state dopant source layer is formed above the semiconductor substrate, conformal with the plurality of semiconductor fins. A dielectric layer is formed above the solid state dopant source layer. The dielectric layer and the solid state dopant source layer are recessed to approximately a same level below a top surface of the plurality of semiconductor fins, exposing protruding portions of each of the plurality of semiconductor fins above sub-fin regions of each of the plurality of semiconductor fins. The method also involves driving dopants from the solid state dopant source layer into the sub-fin regions of each of the plurality of semiconductor fins.

  • Patent number: 10069658
    Abstract: Embodiments include a pulsed decision feedback equalization (DFE) circuit. The DFE circuit may include a current integrating summer (CIS) circuit that passes one or more data signals on respective data nodes based on an input data signal and a clock signal. The DFE circuit may further include a correction circuit, such as a current digital-to-analog converter (IDAC) circuit, that may provide a correction circuit to a data node based on a prior bit of the input data signal. The correction circuit may provide a conductive path between a current source of the correction circuit and the data node for a time period that is less than the unit interval (UI) of the clock signal and/or data signal. The DFE circuit may include a plurality of correction circuits to provide respective correction signals based on different prior bits of the input data signal. Other embodiments may be described and claimed.
