Abstract: Sensor error detection with an additional channel is disclosed herein. First and second magnetic sensing elements can be disposed at angles relative to each other. In some embodiments, the first and second magnetic sensing elements can be magnetoresistive sensing elements, such as anisotropic magnetoresistance (AMR) sensing elements. Sensor data from first and second channels, respectively, having the first and second sensing elements, can be obtained. Third channel can receive a signal from the first sensing element and a signal from the second sensing element, and sensor data from the third channel can be obtained. Expected third channel data can be determined and compared to the obtained third channel data to indicate error.

Abstract: A lidar system can be used to measure a distance to one or more objects in a target region, such as by transmitting light towards the target and then receiving light reflected or scattered from the target. Received light can be stored as charge on storage elements such as capacitors, where received light can be stored on different storage elements depending on a time of arrival of the received light. A reduction in the number of storage elements can be achieved by providing one or more groups of storage elements, where each group of storage elements can correspond to a digit of a time of flight, where the time of flight can be round trip travel time of a light beam travelling from the lidar system to the target region and then back to the lidar system. Each group of storage elements can be arranged in a binary tree of a decimal tree configuration. Additionally, a time of activation of each of the storage elements can be increased with an increasing time of flight, such as to compensate for a decreased strength of the received light as the time of flight increases.

Abstract: Power amplifier circuits can behave in a non-linear manner particularly when operated to produce output signal swings approaching an amplifier saturation region. A pre-distortion signal can be applied to a signal to be transmitted to compensate for such power amplifier non-linearity. In applications where two or more transmitter power amplifiers are used, a beam-former can be configured to modify a digitally pre-distorted transmission signal by applying respective beam-forming weighting factors to the digitally pre-distorted transmission signal to provide input transmission signals for respective ones of the power amplifier circuits. The pre-distortion signal can be established at least in part using one or more of a sensed or estimated representation of a transmitted beam formed by spatially aggregating transmitted outputs from the two or more power amplifier circuits. In this manner, power amplifier efficiency can be enhanced without entirely separate pre-distortion compensation for each of the power amplifier circuits.

Abstract: This disclosure relates to data communication networks. An example data communication apparatus includes physical (PHY) layer circuitry that includes transceiver circuitry, decoder circuitry, and a signal analysis unit. The transceiver circuitry receives encoded data symbols via a network link. The received encoded data symbols are encoded using trellis coded modulation (TCM). The decoder circuitry decodes the received encoded data symbols using maximum-likelihood (ML) decoding to map a received symbol sequence to an allowed symbol sequence using a trace-back depth. A trace-back depth value is a number of symbols in the received symbol sequence used by the ML decoding to identify the allowed symbol sequence from the received symbol sequence. The signal analysis unit determines one or more link statistics of the network link, and sets the trace-back depth value according to the one or more link statistics.

Abstract: Magnetic sensors may be positioned around an opening for a wire to measure the current flowing through the wire. A non-symmetric positioning of the sensors around the target measurement zone can enable an expanded measurement zone compared to conventional current measurement devices. Further, some sensors may be paired such that a hypothetical line connecting the sensors is tangential to the target measurement zone. Other sensors may be paired such that a hypothetical line between the sensors crosses the target measurement zone. The different pairs of the sensors can enable a reduction in the impact of stray field interference on the measurement of the current flowing through the wire.

Abstract: Integrated digital isolators comprise a first transformer coil or capacitor plate mounted on an integrated circuit substrate, and separated from a second transformer coil or capacitor plate via an electrically insulating isolation layer. The electrical isolation that is achieved is dependent upon the material and thickness of the isolation layer. In order to reduce the amount of time required for fabrication while still allowing thick isolation layers to be deployed, in examples of the disclosure pre-formed sheets or tapes of dielectric material are applied to the substrate over the first transformer coil or capacitive plate, for example by being rolled onto the substrate using a heated roller. Such a technique results in a thick isolation layer that is formed using a simple process and much more quickly and reliably than conventional spin-coating or deposition techniques.

Abstract: A electrochemical or other sensor interface circuit architecture can deliver substantial DC offset bias to an electrochemical or other sensor separately or independently from delivering a time-varying AC excitation signal, which can then be provided with higher resolution, which, in turn, can allow better resolution of the measured response signal providing the impedance characteristic of sensor condition. For example, a differential time-varying AC excitation signal for the sensor condition characteristic can be delivered separately and independently from a differential stable (e.g., DC or other) bias signal, such as by using separate digital-to-analog converters (DACs), so that providing the more stable signal does not limit the resolution and accuracy of the time-varying signal, such as by using up the dynamic range of a single DAC.

Abstract: Shortening any of the operational phases of a noise-shaping successive approximation register (SAR) analog-to-digital converter (ADC), including the acquisition phase, the bit trial phase, and the residue charge transfer phase, can result in higher power, and it can be difficult to achieve high speed at low power.Using various techniques described, the acquisition, bit-trial, and residue charge transfer phases of two or more digital-to-analog converter (DAC) circuits of an ADC circuit can be time-interleaved. The use of two or more DAC circuits can increase or maximize the time available for the acquisition, bit-trial, and residue charge transfer phases.

Abstract: A device for controlling an electronic switch between a power supply and a load includes a sensing circuit to measure a current to the load and a control circuit to control operation of the electronic switch if the current exceeds a current limit. The control circuit includes a normal current circuit to output a first switch control current to the electronic switch and a boost current circuit to output a second switch control current to the electronic switch, the first switch control current being higher than the second switch control current.
