  • Patent number: 11916374
    Abstract: A system is provided that includes a power transmitter configured to provide power to a current loop, a power receiver configured to receive the power from the current loop. The power receiver is configured to, on a periodic basis, disconnect from the current loop to stop pulling power from the current loop for a period of time to enable a safety check to be performed by the power transmitter. The power transmitter is configured to: monitor current on the current loop; determine whether a current level on the current loop passes the safety check within a predetermined time interval since a determination that the current level was not within a safe range; and control connectivity of the power to the current loop depending on whether the safety check has or has not passed within the predetermined time interval.

  • Patent number: 11909354
    Abstract: One or more heating elements are provided to heat a MEMS component (such as a resonator) to a temperature higher than an ambient temperature range in which the MEMS component is intended to operate—in effect, heating the MEMS component and optionally related circuitry to a steady-state “oven” temperature above that which would occur naturally during component operation and thereby avoiding temperature-dependent performance variance/instability (frequency, voltage, propagation delay, etc.). In a number of embodiments, an IC package is implemented with distinct temperature-isolated and temperature-interfaced regions, the former bearing or housing the MEMS component and subject to heating (i.e., to oven temperature) by the one or more heating elements while the latter is provided with (e.g., disposed adjacent) one or more heat dissipation paths to discharge heat generated by transistor circuitry (i.e., expel heat from the integrated circuit package).

  • Patent number: 11909224
    Abstract: A wireless optical power transmission system comprising a transmitter and receiver, the transmitter comprising a laser emitting a beam, a scanning mirror for steering the beam towards said receiver and a control unit receiving signals from a detection unit on the receiver and controlling the beam power and the scanning mirror. The receiver has a photovoltaic cell having a bandgap energy of 0.75-1.2 e V, with a plurality of conductors on abeam receiving surface. A cover layer of material blocking illumination of wavelengths outside that of the laser, is disposed on the photovoltaic cell. The cover layer may have anti-reflective coatings on its top and bottom surfaces. The detection unit thus generates a signal representing the power of the laser beam impinging upon the receiver, independent of illuminations other than that of said laser beam. The control unit thus can maintain the laser power impinging on the receiver.

  • Patent number: 11863165
    Abstract: The trend in wireless communication receivers is to capture more and more bandwidth to support higher throughput, and to directly sample the radio frequency (RF) signal to enable re-configurability and lower cost. Other applications like instrumentation also demand the ability to digitize wide bandwidth RF signals. These applications benefit from input circuitry which can perform well with high speed, wide bandwidth RF signals. An input buffer and bootstrapped switch are designed to service such applications, and can be implemented in 28 nm complementary metal-oxide (CMOS) technology.

  • Patent number: 11863167
    Abstract: A drive circuit for a power switching transistor includes a first pull-up drive transistor connected in parallel with a second pull-up drive transistor, a first pull-down drive transistor coupled to the first and second pull-up drive transistors in series to drive the power switching transistor. When control signal is at a high level, the first pull-up driver is turned on, and the first pull-down driver is turned off. The second pull-up drive transistor being in turn-on or turn-off state is determined by comparing voltage of the power supply with the threshold value. When voltage of the power supply is lower than the threshold value, the first and second pull-up drive transistor are driven together. When voltage of the power supply is higher than the threshold value, the second pull-up driving transistor is turned on only after the driving output is slightly larger than the Miller plateau voltage.
