Abstract
As a key component of All-Digital Phase-Locked Loop (ADPLL),Digitally Controlled Oscillator (DCO) provides a high-frequency output clock.The DCO performance directly affects the frequency range and jitter performance of ADPLL.This paper proposes a DCO based on all-digital standard cell library design.The structure includes the coarse,medium and fine adjustment stages,which achieves a high frequency range of 0.5 GHz～2.6 GHz and a high adjustment resolution of 0.8 ps.The DCO is designed and implemented in an advanced process.Based on this DCO,an ADPLL is designed and implemented.The system jitter is less than 2 ps and the power is 10 mW.关键词
