摘要：
A first magnetic sensor is formed on a semiconductor substrate, and the first magnetic sensor produces a first output signal in response to movement of a multi-pole magnet. A second magnetic sensor is formed on the semiconductor substrate so as to be intertwined with the first magnetic sensor and so as to be at a predetermined angle with respect to the first magnetic sensor. The second magnetic sensor produces a second output signal in response to movement of the multi-pole magnet. The predetermined angle is between 0° and 180° exclusive, and the predetermined angle is sufficient to produce a difference in phase between the first and second output signals. An output signal converter converts the first and second output signals to a linear signal.
