| 摘要 | A method used by a phase difference detection circuit for detecting a phase difference between two signals includes shifting a detected phase difference between the two signals by an offset value, outputting the detected phase difference, and controlling the offset value such that the outputted detected phase difference falls within a phase difference range between a lower limit and an upper limit. | ||
