Abstract
A rotation detector for a magnet wheel which is high-resolution, precise and at the same time only requires the space of a single differential Hall IC, has combined on a single electronic component the circuitry equivalent to at least two differential Hall IC's. The electronic component derives a digital signal sequence that has a frequency twice the frequency of a signal that can be derived from a single differential Hall circuit by coupling the output signals of the differential Hall circuits. Additionally, only three Hall sensors are required to form the difference signals necessary to derive the digital signal sequence by using one Hall sensor as a reference for the remaining two Hall sensors.
