  • Patent number: 9820141
    Abstract: A receiver for digital signals includes a radiofrequency stage. A feedback loop controls an amplitude of a modulated radiofrequency signal passing through the radiofrequency stage as a function of a comparison of a baseband signal with a reference value. A baseband stage includes an RC network cascaded to the radiofrequency stage and coupled to a baseband detector that generates the baseband signal. The feedback loop includes a circuit for detecting a range of variation of the comparison. The amplitude of the modulated radiofrequency signal is controlled as a function of an end value (e.g., maximum or minimum) of the detected range of variation. A switching circuit operates to selectively short circuit a resistive component of the RC network during receiver start-up.

  • Patent number: 9818930
    Abstract: A support structure includes an internal cavity. An elastic membrane extends to divide the internal cavity into a first chamber and a second chamber. The elastic membrane includes a nanometric-sized pin hole extending there through to interconnect the first chamber to the second chamber. The elastic membrane is formed of a first electrode film and a second electrode film separated by a piezo insulating film. Electrical connection leads are provided to support application of a bias current to the first and second electrode films of the elastic membrane. In response to an applied bias current, the elastic membrane deforms by bending in a direction towards one of the first and second chambers so as to produce an increase in a diameter of the pin hole.

  • Patent number: 9820303
    Abstract: Multicast transmissions are efficient but do not allow for individual acknowledgement that the data was received by each receiver. This is not acceptable for isochronous systems that require specific levels of QoS for each device. A multimedia communications protocol is provided that uses a novel multi-destination burst transmission protocol in multimedia isochronous systems. The transmitter establishes a bi-directional burst mode for multicasting data to multiple devices and receiving Reverse Start of Frame (RSOF) delimiters from each multicast-destination receiver in response to multiple SOF delimiters, thus providing protocol-efficient multi-destination acknowledgements.

  • Patent number: 9818646
    Abstract: An integrated circuit includes a silicon-on-insulator wafer and interconnect layer providing a support for a coplanar waveguide formed above a top side of the support. A through-silicon via is formed from a back side of the support and passing through the silicon-on-insulator wafer to reach the interconnect layer. A trench is formed from the back side of the support underneath the coplanar waveguide. The trench extends over at least an entire length of the coplanar waveguide. The trench passes through the silicon-on-insulator wafer to reach the interconnect layer and may have a substantially same depth as the through-silicon via.

  • Patent number: 9818937
    Abstract: A miniature oxygen sensor makes use of paramagnetic properties of oxygen gas to provide a fast response time, low power consumption, improved accuracy and sensitivity, and superior durability. The miniature oxygen sensor disclosed maintains a sample of ambient air within a micro-channel formed in a semiconductor substrate. O2 molecules segregate in response to an applied magnetic field, thereby establishing a measurable Hall voltage. Oxygen present in the sample of ambient air can be deduced from a change in Hall voltage with variation in the applied magnetic field. The magnetic field can be applied either by an external magnet or by a thin film magnet integrated into a gas sensing cavity within the micro-channel. A differential sensor further includes a reference element containing an unmagnetized control sample. The miniature oxygen sensor is suitable for use as a real-time air quality monitor in consumer products such as smart phones.

  • Patent number: 9819268
    Abstract: An electronic device includes first and second transistors coupled in series between first and second source voltage levels. An inductor is coupled between a node coupling the first and second transistors and a load. Control logic is operative to generate control pulses operative to switch the first and second transistors. The controller generates the control pulses as a continuous stream of control pulses in a continuous conduction mode, and skips generation of some control pulses in a discontinuous conduction mode in response to a pulse skipping signal. A pulse skipping circuit is operative to generate a sense voltage as a function of an inductor current in the inductor, compare the sense voltage to ground, and generate a pulse skipping signal to the control logic when the sense voltage is below ground.
