Abstract

A smart phase switching method includes setting a first phase switching threshold, a convergence upper bound, and a convergence lower bound, sampling a received signal continuously for acquiring a phase offset accumulated value of the received signal during each period, updating the first phase switching threshold to generate a second phase switching upper bound threshold and a second phase switching lower bound threshold when a plurality of phase offset accumulated values of the received signal during a first predetermined time interval fall into a range from the convergence upper bound to the convergence lower bound, and sampling the received signal continuously for determining if a phase is switched to an opposite operating point according to a phase offset accumulated value of the received signal after the second phase switching upper bound threshold and the second phase switching lower bound threshold are generated.
