A new highly stable magneto-impedance (MI) micro magnetic sensor with a pair of zero-magnetostrictive amorphous wires is presented. The sensor picks up a first pulse in an induced oscillatory pulse voltage at a wire coil using an analog switch. High temperature stability in the MI sensor is established in which zero drift for temperature variation from 20 degrees C to 80 degrees C is 0.6%/FS (0.01.%/FS degrees C). The highly stable MI sensor will be useful for application to automobile controls.
