Abstract
A vertical Hall Effect sensor is provided having a high degree of symmetry between its bias modes, can be adapted to exhibit a small pre-spinning systematic offset, and complies with the minimal spacing requirements allowed by the manufacturing technology (e.g., CMOS) between the inner contacts. These characteristics enable the vertical Hall Effect sensor to have optimal performance with regard to offset and sensitivity.
