Hall Effect Devices with Three Terminals: Their Magnetic Sensitivity and Offset Cancellation Scheme

Figure 1

A Hall plate with five contacts after [2]. The two small sense contacts are only on one single side of the Hall effect regions. (a) shows the geometry. (b) shows the potential and the current streamlines as obtained by a numerical calculation for a Hall angle of 45°. For small Hall angle the current streamlines become parallel to the long edge of the device.
