本文提出了一种全数字锁相环(ADPLL),它的所有功能块都由标准数字单元综合而成,并自动布局和布线(P&R)。为了解决P&R引起的系统失配问题,提出了一种校准方案。ADPLL采用65 nm工艺制作,面积为0.042mm2。在2.5 GHz频率下,周期抖动为3.2ps rms(36pspp),在1.5~2.7 GHz频率范围内功耗为9.1 mW~14.6 mW。
This paper presents an all-digital PLL (ADPLL) in which all functional blocks have been synthesized from standard digital cells and automatically placed and routed (P&R). A calibration scheme is proposed to account for the systematic mismatch resulting from P&R. The ADPLL is fabricated in 65nm CMOS and occupies 0.042mm2. The period jitter is 3.2psrms (36pspp) at 2.5GHz, and the power consumption is 9.1mW to 14.6mW over a 1.5 to 2.7GHz frequency range.
