Abstract
A system for suppressing low frequency noise of magnetoresistive sensors, includes a device for measuring a magnetic field, the device including at least one magnetoresistive sensor, the magnetoresistive sensor having a first sensitivity at a first operating point and a second sensitivity at a second operating point, the sensitivity at the second operating point being low or zero; a modulator configured to switch the at least one magnetoresistive sensor from the first operating point to the second operating point; and a signal processor for processing the signal derived from the device for measuring a magnetic field.
