Abstract: Signal processing circuit for a Hall sensor and signal processing method. Signal processing circuits for four-phase spinning Hall magnetic field sensors, corresponding methods and corresponding magnetic field sensor apparatuses are provided. In this case, a correction signal (c) is generated on the basis of a first feedback signal (fb1) and a second feedback signal (fb2), wherein the first feedback signal (fb1) is provided with a shorter signal propagation time than the second feedback signal (fb2).

Abstract: A bandgap reference circuit includes a bandgap reference core circuit that includes a first bipolar transistor having a first emitter current density and a first base-emitter voltage, a second bipolar transistor having a second emitter current density that is smaller than the first emitter current density and having a second base-emitter voltage, a resistor that is connected to the emitter of the second bipolar transistor, and a differential amplifier circuit that is configured to control first and second emitter currents through the first and second bipolar transistors, respectively, such that a sum of the second base-emitter voltage and a voltage drop across the resistor approximates the first base-emitter voltage. The bandgap reference circuit further includes a first replica bipolar transistor that emulates an operating point of the first bipolar transistor and a second replica bipolar transistor that emulates an operating point of the second bipolar transistor.

Abstract: The present disclosure relates to a magnetic field sensor circuit including at least one coil for measuring a magnetic field, a first stage amplifier circuit coupled to the coil and having a first transfer function with a pole at a first frequency, and a second stage amplifier circuit coupled to an output of the first stage amplifier circuit and having a second transfer function with a zero at the first frequency. In some embodiments, a temperature dependent frequency drift of the pole of the first transfer function corresponds to a temperature dependent frequency drift of the zero of the second transfer function.

Abstract: The present disclosure describes a semiconductor circuit arrangement comprising a Hall sensor circuit integrated into a semiconductor substrate and configured to conduct a Hall supply current between a first terminal and a second terminal of a Hall effect region at an angle of 45° with respect to a normal to a primary flat plane of the semiconductor substrate laterally through the Hall effect region, wherein the Hall supply current has a first dependence on a mechanical stress of the semiconductor substrate. A resistance arrangement integrated into the semiconductor substrate, the resistance arrangement being different than the Hall effect region, is configured to conduct a current between a first terminal and a second terminal of the resistance arrangement, wherein the current through the resistance arrangement has a second dependence on the mechanical stress of the semiconductor substrate. A compensation circuit is configured to correct, on the basis of a signal difference between the first terminal of the Hall effect region and the first terminal of the resistance arrangement, a Hall voltage that is measured between a third and a fourth terminal of the Hall effect region and is dependent on the mechanical stress of the semiconductor substrate.
