Abstract
Magnetic resistive elements,and,cooperatively detect the change of the magnetic field responsive to the rotation of a gear,fixed to a shaft,An amplification circuit,comprises an operational amplifier,having an input terminal to which a gain-determining input resistor,is connected. A gain-determining feedback resistor,is provided in a feedback path of the operational amplifier,The gain-determining resistors,and,are formed by a P well region and a P,region of a MOS process element. The temperature characteristics of the gain-determining resistor,and,are opposed to that of the magnetic resistive elements,and,The temperature characteristics of the gain of the operational amplifier,cancel the temperature characteristics of the magnetic resistive elements,and
