Title: Magnetic sensor
Inventor: TOKI KAORU
IPC: H01L43/08
Filed: 1979-04-09
Abstract: PURPOSE: To effectively produce a signal output from a magnetic sensor without being affected by a DC offset voltage detecting in AC manner a signal magnetic field in such a way that an AC bias magnetic field having infinitesimal amplitude is amplitude modulated as a carrier and demodulating it.  
     CONSTITUTION: When a magnetic field 23 is applied to a magnetoresistance effect element 6 as a signal magnetic field in a stripe width direction, the magnetic field 23 is regenerated and AC amplified while applying an AC bias magnetic field having infinitesimal amplitude of higher frequency than the maximum frequency of the signal magnetic field thereto. An output 14 is produced from an amplifier 13 with the AC bias magnetic field as a carrier, and amplitude modulated by the magnetic field 23 to produce the output 14. This output signal 14 is rectified by a rectifier 16, integrated by an integrator 18 and demodulated by a demodulator, which produces a demodulated output 26.
