Abstract
A phase adjustment apparatus for providing a clock signal to a core circuit is provided. The core circuit is powered by a core voltage. The phase adjustment apparatus includes two clock receiving ends, a plurality of digital receiving ends and a combination circuit. The two clock receiving ends receive two original clocks having a same frequency while the two original clock signals possess different phases. The digital receiving ends receive a plurality of phase selection signals. The synthesizing circuit is powered by a first voltage lower than the core voltage, and generates the clock signal according to the phase control signals and the two original clock signals.
