The highest detection resolution of a magnetic field sensor using a magnetic core is dependent on the noise of the magnetic core and the electronic circuits. Sensor sensitivity cannot be discussed without attention to these points. This paper describes the optimum excitation parameters for improvement of the dc biased-type differential magnetic field sensor resolution. Investigation of optimum excitation conditions, so that the ratio of magnetic core noise to detection sensitivity is minimum, showed that the resolution can be improved by operating at a deeper bias with a higher excitation frequency. It was possible to reduce the sensor noise level to 1×10-13T/√Hz.
