    摘要: The present disclosure is directed to embodiments of a conductive structure on a conductive barrier layer that separates the conductive structure from a conductive layer on which the conductive barrier layer is present. A gap or crevice extends along respective surfaces of the conductive structure and along respective surfaces of one or more insulating layers. The gap or crevice separates the respective surfaces of the one or more insulating layers from the respective surfaces of the conductive structure. The gap or crevice provides clearance in which the conductive structure may expand into when exposed to changes in temperature. For example, when coupling a wire bond to the conductive structure, the conductive structure may increase in temperature and expand into the gap or crevice. However, even in the expanded state, respective surfaces of the conductive structure do not physically contact the respective surfaces of the one or more insulating layers.

    摘要: A processing system includes a reset circuit, a memory storing configuration data, and a hardware configuration circuit transmitting the configuration data to configuration data clients. The system executes a reset phase, configuration phase, and software runtime phase. First and second reset terminals are associated with first and second circuitries which are respectively associated with configuration data clients. The configuration data includes first and second mode configuration data for the first and second terminals. During the reset and configuration phase, the first circuitry activates a strong pull-down, and the second circuitry activates a weak pull-down. During the software runtime phase, the first circuitry activate a weak pull-down for implementing a bidirectional reset terminal or activates a weak pull-up resistance for implementing a reset output terminal, and the second circuitry activates a weak pull-up for implementing a reset input terminal or activates a strong pull-up for implementing a reset output terminal.

    摘要: A device such as a dosimeter for detecting ionizing radiation, for example, X-ray radiation, in hospitals or the like. The device includes scintillator material configured to produce light as a result of radiation interacting with the scintillator material, and photoelectric conversion circuitry optically coupled to the scintillator material and configured to produce electrical signals via photoelectric conversion of light produced by the scintillator material. The device includes a plurality of photoelectric converters optically coupled with the scintillator material at spatially separated locations. The plurality of photoelectric converters thus produce respective electrical signals by photoelectric conversion of light produced by the scintillator material as a result of radiation interacting with the scintillator material. Improved energy linearity is thus facilitated while providing more efficient detection over the whole energy spectrum of radiation detected.

    摘要: Disclosed herein is a DC-DC converter including a power section and a bootstrap circuit for driving the gate of the high-side transistor of the power section. The bootstrap circuit includes an adaptive clamp circuit that maintains a proper voltage differential across the bootstrap capacitor within the bootstrap circuit for recharge during off-times regardless of whether the mode of operation of the DC-DC converter continuous conduction mode (CCM), discontinuous conduction mode (DCM), or pulse-skip mode. This voltage differential is established as being between a bootstrap voltage and a voltage at a tap between the high and low side transistors of the power section. The adaptive clamp circuit maintains the bootstrap voltage as following the lesser of the output voltage and the voltage at the tap.

    摘要: A BGA package includes an array of electrically conductive balls providing electrical contact for a semiconductor die. A power channel is provided to convey power supply current towards the semiconductor die. The power channel is formed by a stack of electrically conductive planes. The electrically conductive planes are stacked in a stepped arrangement wherein a number of stacked planes in each step of the stack increases in a direction from a distal end to a proximal end of the power channel. Adjacent electrically conductive planes in the stack of the power channel are electrically coupled with electrically conductive vias extending therebetween. Current conduction paths towards the die area thus have resistance values that decrease from the distal end to the proximal end of the power channel.

    摘要: A microelectromechanical gyroscope with detection along a vertical axis is provided with a detection structure having a movable structure, suspended above a substrate so as to perform, as a function of an angular velocity around the vertical axis a sense movement along a first horizontal axis. The movable structure has at least one drive mass internally defining a window, elastically coupled to a rotor anchor, at an anchoring region, through elastic anchoring elements; at least one bridge element, rigid and of a conductive material, cantilevered suspended and extending within the window along the first horizontal axis, elastically coupled to the drive mass; movable electrodes, carried integrally by the bridge element with extension along a second horizontal axis. The detection structure also has stator electrodes, arranged in the window and interdigitated with the movable electrodes, at a certain separation distance below the bridge element, which extends longitudinally above the same stator electrodes and the movable electrodes.

    摘要: A method includes receiving electrostatic sensor data in a processor of an electronic device from an electrostatic sensor mounted behind a touchscreen of the electronic device and using the electrostatic sensor data to determine when the touchscreen is being used. Based on whether or not the touchscreen is being used, an on-table detection (OTD) algorithm is selected from a plurality of available OTD algorithms. In one or more examples, the OTD algorithm may also be selected based on the current device mode of the electronic device, which may be determined from a lid angle, a screen angle, and a keyboard angle of the electronic device. The selected OTD algorithm is run to determine whether or not the electronic device is located on a stationary or stable surface.
