Abstract:
    A phase detection device comprising an analog-digital converter, an interpolator, and a determining unit. The analog-digital converter receives an analog signal and converts the analog signal to a digital signal according to a plurality of digital sampling points. The interpolator generates a plurality of interpolation points according to a predetermined amount of digital sampling points. The determining unit obtains a phase of the ZC point according to the interpolation points or the digital sampling points.
