In three-dimensional (3-D) integrated magnetic sensor de- sign, cross-axis sensitivities among the various components of the magnetic field have been a problem. In this brief it is demonstrated that complete elimination of the cross-sensitivity is possible if a 3-D magnetic sensor is implemented in BiCMOS technology. A compact device structure is designed to detect the three components of the magnetic field vector by placing a split-collector magnetotransistor and a split-drain MOSFET adjacent to each other. Measured sensitivities of the sensor are presented.
