Abstract
A differential amplifier generates an offset correction signal based on a rotation detection signal from a rotation detector apparatus and an offset signal. A comparator compares the offset correction signal with a threshold voltage, and outputs a binarized signal representing the comparison result. An average value signal generator circuit generates an average value signal representing the average value of the offset correction signal. The offset signal generator circuit generates the offset signal so that the signal voltage of the average value signal has a voltage value between a threshold voltage and a threshold voltage.
