Abstract: A voltage sensor device includes an oscillator unit, the oscillator unit having a tunable bulk acoustic wave (BAW) resonator device and an oscillator core. The voltage sensor device also includes a frequency analyzer configured to obtain frequency measurements for the oscillator unit and to determine a voltage sense value based on a comparison of at least some of the obtained frequency measurements. The voltage sensor device also includes an output interface configured to store or output voltage sense values determined by the frequency analyzer.

Abstract: In described examples, a method of operating a charge pump includes a first control signal deactivating a first transistor, and the first control signal's logical complement activating a second transistor to reset the first transistor's DC bias voltage. The first control signal's logical complement deactivates the second transistor, and the first control signal provides a bias voltage to the first transistor to activate it, causing current to be transmitted from an input voltage to an output terminal. A second control signal deactivates a third transistor, and the second control signal's logical complement activates a fourth transistor to reset the second transistor's DC bias voltage. The second control signal's logical complement deactivates the fourth transistor, and the second control signal provides a bias voltage to the third transistor to activate it, causing current to be transmitted from the output terminal to a ground.

Abstract: A system includes a tunable bulk acoustic wave (BAW) resonator device and a direct-current (DC) tuning controller coupled to the tunable BAW resonator device. The system also includes an oscillator circuit coupled to the tunable BAW resonator device. The DC tuning controller selectively adjusts a DC tuning signal applied to the tunable BAW resonator device to adjust a signal frequency generated by the oscillator circuit.

Abstract: For producing a low-power, low-phase noise oscillating signal using a self-injection locking oscillator, examples include: producing, using an oscillator, a signal having a base frequency component, an Mth harmonic component and a Pth harmonic component, in which M and P are selected integers and M>P>1; filtering the signal through one or more bandpass filters including at least two resonators, the filters having Q factor ≥5, the filters configured to pass the Mth and Pth harmonic components; multiplying the filtered Mth and Pth harmonic components together to produce a multiplied signal, and filtering the multiplied signal using a low pass filter to pass a difference between the filtered Mth and Pth harmonic components, the difference including a filtered beat frequency waveform; and injecting the filtered beat frequency waveform into the oscillator to injection lock the signal to the filtered beat frequency waveform.

Abstract: One example includes a system is comprised of an elongated transmission line and as module. The elongated transmission line includes an arrangement of transmission line couplers distributed along its length at spaced apart locations. The module has an outer surface and is comprised of a transmitter, and a transmitter coupler. The transmitter transmits a radio frequency signal. The transmitter coupler is on the outer surface of the module, electrically connects with the transmitter, and aligns to couple with a respective one of the transmission line couplers to provide a contactless communication link between the transmitter and the elongated transmission line.

Abstract: A system is provided in which a set of modules each have a substrate on which is mounted a radio frequency (RF) transmitter and/or an RF receiver. Each module has a housing that surrounds and encloses the substrate. The housing has a port region on a surface of the housing. Each module has a tapered near field communication (NFC) field confiner located between the substrate and the port region on the housing configured to guide electromagnetic energy produced by the RF transmitter to the port region so that it can be emanated to a port region of an adjacent module.
