Abstract
A rotation sensor has a magnetoelectric conversion unit that converts change of magnetic flux whose direction changes periodically with rotation of a rotator into an electric signal and a processing unit that processes the electric signal. The magnetoelectric conversion unit outputs a first detection signal and a second detection signal. The processing unit has a first comparison unit that compares a detection threshold and the first detection signal and a second comparison unit that compares a reference threshold and the second detection signal. The first comparison unit changes a voltage level of the detection threshold when the first detection signal exceeds or falls below the detection threshold and then restores the voltage level of the detection threshold based on the second detection signal and the reference threshold, and the first comparison unit converts the first detection signal into a pulse signal based on the detection threshold of the same voltage level.
