Abstract

The analysis of electronic aspects of the SOC-type magnetoresistive magnetic field sensors designing is presented. The analytical equations between parameters of thin-film magnetoresistive bridge both loading and noise parameters of an emplifying part of the integrated sensor are formulated. In this case the best sensitivity and a dy­namic range of measurements of a magnetic field are reached at the given electric power consumption. It is shown that at realized technological parameters the sensitivity of the SOC-type magnetoresistive magnetic field sensors based on an anisotropic magnetoresistive effect at measurement of quasiconstant magnetic fields can achieve at power consumption 10—100 mW an order 10-4—10-5 Oe (at intensity of a magnetic field of saturation 10 Oe). Keywords: magnetoresistive' magnetic field' sensor' sensitivity' electronics.
