Abstract

A control method, which is adapted to a phase interpolator configured to generate an output signal based on a current distribution ratio, includes following operations: selecting a first input pair and a second input pair from the phase interpolator; sequentially switching currents associated with the current distribution ratio from the first input pair to flowing through the second input pair, in order to adjust a phase of the output signal to correspond to a first phase interval; and after all of the currents flow through to the second input pair, selecting the second input pair and a third input pair from the phase interpolator, and adjusting the current distribution ratio to correspond the phase of the output signal to a second phase interval, in which the first phase interval and the second phase interval are continuous.
