Abstract
A movement sensor comprises a multi-pole ring magnet, a semiconductor substrate, a first magnetic sensor formed on the semiconductor substrate, and a second magnetic sensor formed on the semiconductor substrate. The first magnetic sensor is configured to produce a first output signal in response to movement of the multi-pole ring magnet, and a centroid of the first and second magnetic sensors are separate and radially aligned on the semiconductor substrate relative to the multi-pole ring magnet. The second magnetic sensor is arranged at a predetermined angle with respect to the first magnetic sensor and is configured to produce a second output signal in response to the movement of the multi-pole ring magnet. The predetermined angle is between 0° and 90° exclusive and is configured to produce a difference in phase between the first and second output signals in response to the movement of the multi-pole ring magnet.
