  • Patent number: 11227776
    Abstract: Embodiments of the present disclosure are directed to a leadframe package with recesses formed in outer surface of the leads. The recesses are filled with a filler material, such as solder. The filler material in the recesses provides a wetable surface for filler material, such as solder, to adhere to during mounting of the package to another device, such as a printed circuit board (PCB). This enables strong solder joints between the leads of the package and the PCB. It also enables improved visual inspection of the solder joints after the package has been mounted.

  • Patent number: 11199410
    Abstract: A device including microelectromechanical systems (MEMS) sensors is used in dead reckoning in conditions where Global Positioning System (GPS) signals or Global Navigation Satellite System (GNSS) signals are lost. The device is capable of tracking the location of the device after the GPS/GNSS signals are lost by using MEMS sensors such as accelerometers and gyroscopes. By calculating a misalignment angle between a sensor frame of the device with either the movement direction of the vehicle or the walking direction of a pedestrian using the MEMS sensors, the device can accurately calculate the location of a user of the device even without the GPS/GNSS signals. Accordingly, a device capable of tracking the location of a pedestrian and a user riding in a vehicle without utilizing GPS/GNSS signals can be provided.

  • Publication number: 20210343829
    Abstract: An interconnect structure for use in coupling transistors in an integrated circuit is disclosed, including various configurations in which ferroelectric capacitors exhibiting negative capacitance are coupled in series with dielectric capacitors. In one embodiment, the negative capacitor includes a dielectric/ferroelectric bi-layer. When a negative capacitor is electrically coupled in series with a conventional dielectric capacitor, the series combination behaves like a stable ferroelectric capacitor for which the overall capacitance can be measured experimentally, and tuned to a desired value. The composite capacitance of a dielectric capacitor and a ferroelectric capacitor having negative capacitance coupled in series is, in theory, infinite, and in practice, very large. A series combination of positive and negative capacitors within a microelectronic interconnect structure can be used to make high capacity DRAM memory cells.

  • Patent number: 11162790
    Abstract: A drive signal is applied to a MEMS gyroscope having several intrinsic resonant modes. Frequency and amplitude of mechanical oscillation in response to the drive signal is sensed. At startup, the drive signal frequency is set to a kicking frequency offset from a resonant frequency corresponding to a desired one of the intrinsic resonant modes. In response to sufficient sensed amplitude of mechanical oscillation at the kicking frequency, a frequency tracking process is engaged to control the frequency for the drive signal to sustain mechanical oscillation at the frequency of the desired one of the plurality of intrinsic resonant modes as the oscillation amplitude increases. When the increasing amplitude of the mechanical oscillation exceeds a threshold, a gain control process is used to exercise gain control over the applied drive signal so as to cause the amplitude of mechanical oscillation to match a further threshold. At that point start-up terminates.
