Abstract: PURPOSE:To remove a power supply noise with a small number of elements by connecting between the inverted inputs of two operational amplifiers by a serial circuit consisting of a resistor and a DC interrupting capacitor and mutually using voltages appearing in respective inverted inputs in common. CONSTITUTION:The respective inverted inputs of the operational amplifiers OP1, OP2 are connected by the serial circuit consisting of the resistor R8 and the capacitor C.

Abstract: PURPOSE:To remove a noise signal due to an external magnetic field, by arranging a high permeability magnetic body to at least the single surface of an MR sensor (magneto resistance effect element) through an insulating layer and utilizing the diamagnetic field thereof. CONSTITUTION:An Mr sensor 2 is laminated to a non-magnetic substrate 1 by a membrane depositing method and a high permeability magnetic layer 5 is formed thereon through an insulating layer 4. When a magnetic field is applied to the MR sensor 2 from the outside, the magnetic layer 5 is magnetized in the same direction as an external magnetic field.
