The invention discloses a phase detection method including a quadrant determining procedure, a first comparison procedure, a second comparison procedure, a coordinate transforming procedure, and a phase computing procedure. A first and a second phase approximate values are obtained in the quadrant determining procedure and the first comparison procedure. A third phase approximate value is obtained in the second comparison procedure and the coordinate transforming procedure. A total phase is computed in the phase computing procedure. Using this method, we does not need to consult look-up tables to determine the phase, thus saving a lot of memory space. The invention also provides a phase detection device.
