Wireless magnetoresistive microsystem for magnetic field measurements

The design and technology of magnetic semiconductor elements of wireless magnetoresistive microsystems for magnetic field measurements are proposed and the results of the investigations of a highly sensitivity magnetoresistive converter with magnetic field concentrators are presented. The characteristics of the developed measuring amplifier for operation with a signal from a low-resistance magnetoresistive bridge with a certain unbalance value are reported. The technology for fabricating magnetic semiconductor ICs based on thin-film magnetoresistive structures is described.
