Abstract
Abstract In this report, an integrated magnetic sensor which offers the direction of the applied magnetic field is presented. This integrated sensor contains a two-dimensional magnetic detector which detects the in-plane magnetic vectors, Bx and By, and a signal conversion circuit which calculates the direction θ (=tan−1(By/Bx)) using the translinear circuit technology. This integrated magnetic sensor has not only the direction output but the output for the intensity (the absolute value) of the applied magnetic field. The test device was fabricated using the standard bipolar analog IC technology and its characteristics were examined. As a result, the direction of the applied magnetic field was obtained with maximum error of ± 2% full-scale deflection.
