Abstract: In a described example, a circuit includes a sensor circuit including multiple magnetic field sensors having respective sensor outputs. The magnetic field sensors are configured to provide magnetic field sensor signals at the respective sensor outputs representative of a measure of current flow through a conductive structure. A combiner interface has combiner inputs and a combiner output. The combiner inputs are coupled to the respective sensor outputs. The combiner interface is configured to provide an aggregate sensor measurement at the combiner output responsive to the magnetic field sensor signals, in which the aggregate sensor measurement is decoupled from magnetic fields generated responsive to the current flow through the conductive structure.

Abstract: In described examples, a ring oscillator includes a series of N stages in a first ring. Each stage includes a respective output terminal coupled to a respective input terminal of a next one of the stages in the first ring. N is a positive odd-numbered integer of at least three. A series of N level shifters in a second ring are respectively connected to the N stages. Each level shifter receives a respective clock output from a respective output terminal of a stage to which it is connected and generates a respective boosted clock output in response thereto. The boosted clock output is coupled to control an impedance state of a next one of the level shifters in the second ring.

Abstract: An optical position sensing system is disclosed. The system includes a substrate having a surface. A plurality of photodetectors are at multiple locations across the surface, each of the plurality of photodetectors providing detector pulse signals in response to receiving the light. The system further includes a processor that determines a phase shift between the transmitted light pulse signals and the respective detector pulse signals and applies a multi-path resolution operation to distinguish between the detector pulse signals representing the transmitted light pulse signals and those representing reflected light pulse signals. The processor also calculates a distance of a transmitting device from each of the photodetectors based on the determined phase shift and the multi-path resolution operation and calculates a multi-dimensional position of the transmitting device relative to the substrate based on the calculated distances.

Abstract: An ultrasonic detection circuit includes a transmitter circuit that provides excitation signals to an ultrasonic transducer during an excitation interval. A control circuit includes a port to receive a command. The control circuit controls the frequency and the duty cycle of the excitation signals of the transmitter circuit during the excitation interval. The control circuit generates a first excitation signal sequence of the excitation interval followed by a first monitoring period to receive a first echo signal in response to the command. The control circuit generates a second excitation signal sequence of the excitation interval followed by a second monitoring period to receive a second echo signal in response to the command. The control circuit outputs results via the port based on at least one of the first or second echo signals received.

IPC: G01R27/16
Abstract: A microcontroller-based system for measuring the impedance of a device under test (DUT), responsive to a square wave stimulus, includes parallel stimulus signal paths, selectable by a switch, that can correspond to different stimulus frequency ranges. At least one of the paths includes an off-chip PLL and integer divider circuit to modify the frequency of the stimulus. A discrete Fourier transform executed by a processor is used to determine the impedance of the DUT at the stimulus frequency. Multiple frequencies can be analyzed at the same time by using a summation circuit and/or by analyzing odd harmonics of the stimulus frequency.

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.
