Abstract
Magnetic field sensor devices and associated methods are disclosed. In some implementations, a second magnetic field sensor is provided, for example between bridge parts of a first magnetic field sensor.
Claims23
A magnetic field sensor device, comprising:
- a first magnetic field sensor, the first magnetic field sensor comprising a bridge circuit, a first bridge part of the bridge circuit being spatially separate from a second bridge part of the bridge circuit, and
- a second magnetic field sensor.
A method, comprising:
- measuring a modulation of a magnetic field using a bridge circuit with spatially separated bridge branches, and
- measuring a strength of the magnetic field using a magnetic field sensor located between the spatially separated bridge branches.
A method, comprising:
- providing a first magnetic field sensor with spatially separate bridge parts, and
- providing a second magnetic field sensor between the spatially separate bridge parts.
