Abstract
Magnetic field sensor including a magnetic field sensing circuit () comprising a reference magnetic field generator () and a magnetic field sensing cell (), and a signal processing circuit () connected to the output of the magnetic field sensing cell and comprising a demodulator circuit and a gain correction feedback circuit () for correcting error fluctuations in the transfer characteristic of the magnetic field sensor. The sensor further comprises a reference current generator () configured to generate a reference current I ref, the reference current generator connected to the magnetic field sensing circuit () configured for generating the reference magnetic field B ref and to the gain correction feedback circuit configured for providing a reference signal (y) to which an output signal of the demodulator circuit may be compared.
