Abstract
According to an embodiment of the invention, an angle detection apparatus detects the angle of a rotation axis of a rotating device to generate a first signal and a second signal perpendicular to the first signal using the angle detection unit. The first AD conversion unit receives the first signal to perform an analog-to-digital conversion of the first signal. The second AD conversion unit receives the second signal to perform an analog-to-digital conversion of the second signal. The first offset correction unit receives a third signal output from the first AD conversion unit to perform an offset correction of the third signal when the third signal is outside a predetermined range. The second offset correction unit receives a fourth signal output from the second AD conversion unit to perform an offset correction of the fourth signal when the fourth signal is outside the predetermined range.
