Abstract: A magnetic field sensor package includes a sensor housing; a first sensor chip having an integrated first differential magnetic field sensor circuit, the first sensor chip being arranged in the sensor housing; a second sensor chip having an integrated second differential magnetic field sensor circuit, the second sensor chip being arranged in the sensor housing; a common leadframe arranged in the sensor housing and interposed between the first sensor chip and the second sensor chip; and an insulating layer arranged in the sensor housing interposed between the first sensor chip and the common leadframe. The first sensor chip is coupled to the common leadframe via the insulating layer. Additionally, the insulating layer electrically insulates the first sensor chip from the common leadframe such that the first sensor chip and the second sensor chip are galvanically decoupled from each other.

Abstract: A sensor device is provided with a magnetic field sensitive element being positioned in a magnetic field of a magnet. The magnetic field sensitive element is configured to sense an orientation angle of the magnetic field in the range between 0° and 360° and generate a sensing signal. The electronic circuitry is configured to receive and process the sensing signal from the magnetic field sensitive element to generate an angle signal indicating the orientation angle of the magnetic field and an angular speed of the shaft.

Abstract: A system includes a magnetic field sensor arrangement and a controller. The magnetic field sensor arrangement includes a first sensor chip having an integrated circuit differential magnetic field sensor circuit configured to generate a first output signal comprising first signal pulses, a second sensor chip having an integrated second differential magnetic field sensor circuit configured to generate a second output signal comprising second signal pulses, and at least one output signal terminal configured to output the first and the second output signals. The controller receives the first and the second signal pulses from the at least one output signal terminal, evaluates the first and the second signal pulses, and detects an error of an operation of the magnetic field sensor arrangement in response to the first and the second signal pulses not satisfying an expected output pattern of the first and the second signal pulses.

Abstract: Magnetic field sensor devices, corresponding systems and corresponding methods are discussed where a plurality of magnetic field sensors senses a magnetic field. An evaluation circuit generates a first signal component associated with a periodicity of a magnetic field, and a second signal component at least for periods of the magnetic field exceeding a threshold period length, the second signal component having a resolution smaller than the first signal component.

Abstract: An RF transmitter suitable for Bluetooth transmissions has an IF modulator and an RF modulator, the IF modulator being arranged to use a very-low-IF-frequency, smaller than half the channel bandwidth, such that spurious unwanted modulation components fall in other channels having a channel number within one or two of a channel being transmitted. This can reduce the VCO pulling problem and reduce adjacent channel power degradation compared to using higher IF frequencies. The local oscillator PLL's fractionality is used in order to optimize the adjacent power frequency plan by selecting the most appropriate IF frequency. For the Bluetooth application, the IF frequency is <500 kHz, and the main non-filtered spurious components (1LO·xBB with x: ?3, ?2, . . . , +3) image, carrier, pulling, for both 0 and 1 FM signals, are positioned in frequency bands of adjacent channels.
