MAGNETIC DETECTOR

摘要

[PROBLEMS] To provide a magnetic detector which can easily generate a magnetic field detection signal for a magnetic field intensity change of an external magnetic field as compared to the conventional technique and can standardize an integrated circuit. [MEANS FOR SOLVING PROBLEMS] A first output waveform A is obtained from a first output extraction unit of a first series circuit. A second output waveform B is obtained from a second output extraction unit of a second series circuit. When an external magnetic field H in the (+) direction has a first magnetic field intensity H1 and an external magnetic field H in the (-) direction has a second magnetic field intensity H2, the first output waveform A is mixed with the second output waveform B. The intensity relation between the outputs of the first waveform A and the second waveform B when the magnetic field intensity is greater than the first magnetic field intensity H1 and the second magnetic field intensity H2 is reversed when the magnetic field intensity is smaller than the first magnetic field intensity H1 and the second magnetic field intensity H2. Thus, it is possible to easily generate a magnetic field detection signal for a magnetic field intensity change of an external magnetic field as compared to the conventional technique.
