Abstract
The offset in silicon Hall plates is reduced by multiple orthogonal switching of a single symmetrical spinning-current Hall plate. The offset virtually cancels out when the current direction is made to spin with steps of π/8, while the consecutively available Hall voltages are averaged over time. The novel 16-contact spinning-current Hall plate shows less than 50 μ V (100 μ T) residual offset. A combination of the spinning-current Hall plate and the hybrid electronic circuitry obtains a 10 times lower offset (at maximum 200 μ T) when compared to optimized commercially available Hall plates without electronics.
