多相クロックに基づくディジタル制御発振器に関する一提案

抄録

In this paper, the digitally controlled oscillator (DCO) using 1+n/k frequency divider (k>n) based on multi-phase clock is proposed. In this DCO, the time resolution of the output signal is the time of one phase difference of the multi-phase clock. Also, the oscillation frequency range is wide and the duty ratio becomes almost 50%.
