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: An integrated circuit (IC) includes a semiconductor substrate having a first surface and a second surface opposite the first surface. A through wafer trench (TWT) extends from the first surface of the semiconductor substrate to the second surface of the semiconductor substrate. Dielectric material is in the TWT. An interconnect region has layers of dielectric on the first surface of the substrate. The interconnect region has a conductive transmit patch. An antenna is formed, at least in part, by the dielectric material in the TWT and the transmit patch in the interconnect region. The antenna is configured to transmit or receive electromagnetic radiation between the transmit patch and the second surface of the semiconductor substrate through the dielectric material within the trench.

Abstract: An integrated circuit (IC) includes a substrate having a first surface and a second surface opposite the first surface. The substrate has a first region containing a first circuit and a second region containing a second circuit. The first circuit operates at a first supply voltage. The second circuit operates at a second supply voltage. The second supply voltage is higher than the first supply voltage. The IC includes a through wafer trench (TWT) extending from the first surface of the substrate to the second surface of the semiconductor substrate. The TWT separates the first region from the second region. A dielectric material is in the TWT. An interconnect region has layers of dielectric on the first surface of the substrate. The interconnect region is continuous over the first region, the second region, and the TWT. A non-galvanic communication channel is between the first and second circuits.

Abstract: An avalanche photo-diode (APD) circuit includes a first APD and a bias circuit. The first APD is configured to detect light. The bias circuit is configured to control a gain of the first APD. The bias circuit includes a second APD, a reference voltage source, a bias voltage generation circuit, and a metal layer configured to shield the second APD from the light. The reference voltage source is configured to bias the second APD. The bias voltage generation circuit is configured to generate a bias voltage for biasing the first APD based on dark current output by the second APD.

Abstract: A pulsed light source illuminates a scene with a virtual array of points. Light reflected by the scene is detected by a small pixel array, allowing generation of a three-dimensional map of the scene. A processing element processing data output by the small pixel array uses a multipath resolution algorithm to resolve individual objects in the scene.

Abstract: An oscillator circuit includes a first BAW oscillator, a first coupling stage, a second BAW oscillator, and a second coupling stage. The first BAW oscillator is configured to generate a first output signal at a frequency. The first coupling stage is coupled to the first BAW oscillator, and is configured to amplify the first output signal. The second BAW oscillator is coupled to the first coupling stage, and is configured to generate a second output signal at the frequency. The second output signal differs in phase from the first output signal. The second coupling stage is coupled to the first BAW oscillator and the second BAW oscillator, and is configured to amplify the second output signal and drive the first BAW oscillator.
