The thesis is based on the architecture of All-Digital Frequency and Phase Synthesizer (All-Digital PLL) which is published by Hugh Mair and Liming Xiu. The architecture makes multiple signals of the same frequency and the same phase difference the output of a voltage-control-oscillator to be the internal input of the DCO (flying-adder architecture), and we utilize the control word to decide the desired synchronized output signal.

中文摘要本论文是以Hugh Mair及Liming Xiu所提出之全数位频率与相位合成器架构(All-Digital PLL)为基础来做改良设计，此架构是以多个压控振荡器输出的相同频率及相同相位差的讯号，做为DCO(flying-adder architecture)的内部输出讯号，再以控制位元决定出所欲同步讯号。
