CPC G01R 33/063 (2013.01) | 4 Claims |
1. A magnetic sensor circuit comprising:
a first element including only a capacitor;
a second element including a magnetic sensor sensing a magnetic field by a magnetic impedance effect;
a third element including only a capacitor; and
a fourth element including a magnetic sensor sensing a magnetic field by a magnetic impedance effect, wherein
a first series circuit part including the first element and the second element that are connected in series and a second series circuit part including the third element and the fourth element that are connected in series are connected in parallel, and,
in a case where the magnetic field sensed by the magnetic sensor has a predetermined reference value, a product of impedance Z1 of the first element and impedance Z4 of the fourth element and a product of impedance Z2 of the second element and impedance Z3 of the third element are equal.
