Abstract
The invention provides a Hall effect magnetic field sensor (10, 50) including carrier excluding or extracting means (36, 66) for reducing an intrinsic contribution to carrier concentration in the active region (14e, 53c) to provide for the sensor to be operative in an extrinsic saturated regime. This provides an advantage that magnetic field measurement sensitivity of the sensor (10, 50) can be made substantially insensitive to sensor temperature thereby improving measurement accuracy.
