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

Abstract: Various examples are directed to systems and methods for wideband digital predistortion. A digital pre-distortion circuit may be programmed to receive a complex baseband signal and generate a pre-distorted signal. Generating the pre -distorted signal may comprise applying to the complex baseband signal a first correction for an Nth order distortion of a power amplifier at an Ith harmonic frequency zone centered at about an Ith harmonic of a carrier frequency and applying to the complex baseband signal a second correction for the Nth order distortion at a Jth harmonic frequency zone centered at about a Jth harmonic of the carrier frequency different than the Ith harmonic of a carrier frequency.

Abstract: A transformer based digital isolator is provided that has improved immunity to common mode interference. The improved immunity is provided by placing the transformer in association with an H-bridge drive circuit, and taking additional effort to tailor the on state resistance of the transistors to control a common mode voltage at the transformer.

Abstract: An isolator device is provided comprising a body of first dielectric material between the first and second conductors, such as primary and secondary coils of a micro-transformer. A region of second dielectric material is provided between the body of first dielectric material and at least one of the first and second electrodes, wherein the second dielectric material has a higher relative permittivity than the first dielectric material. This provides enhances ability to withstand the Electric fields generated at the edge of a conductor. The body of the first dielectric can be tapered to provide stress relief to prevent the second dielectric material developing stress cracks.

Abstract: A magnetic field sensor is disclosed. The magnetic field sensor includes a first magnetoresistive element and a second magnetoresistive element arranged as a half bridge. The magnetic field sensor also includes two or more conductors adjacent to the first magnetoresistive element and the second magnetoresistive element. The two or more conductors can carry a bias current and a compensation current such that the bias current and the compensation current flow in the same direction adjacent to the first magnetoresistive element while the bias current and the compensation current flow in opposite directions adjacent to the second magnetoresistive element.

Abstract: A combined isolator and power switch is disclosed. Such devices are useful in isolating low voltage components such as control compilers from motors or generators working at high voltages. The combined isolator and power switch includes circuits to transfer internal power from its low voltage side to the switch driver circuits on the high voltage side. The combined isolator and switch is compact and easy to use.

Abstract: Apparatus and methods for compensating radio frequency (RF) transmitters for local oscillator (LO) leakage are provided herein. In certain configurations herein, a transmitter generates an RF transmit signal based on mixing an input signal with an LO signal. Additionally, the transmitter is calibrated to compensate for LO leakage, which provides a number of benefits, including lower levels of undesired emissions from the transmitter.

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.
