| 摘 要： | 设计并讨论了一种新颖的完全基于CMOS静态逻辑反相器设计的数字控制振荡器DCO结构(Digitally-Controlled Oscillator),这种数字控制振荡器采用全数字电路构成,较之LC振荡器更加易于设计和制造,适合于高频高性能数字锁相环的应用。电路结构的仿真采用Spectre仿真器,基于STMicroelectronics CMOS 90nm工艺,在1.2V电源电压下实现了1GHz～6GHz的数控振荡频率变化范围,功耗为0.1mW～3mW,10MHz的频率偏移处的相位噪音约为-114dBc/Hz。

| Abstract: | A novel structure of CMOS-static-logic inverter based DCO(Digitally-Controlled Oscillator)is designed in this thesis.This DCO structure is analysis with Cadence Spectre Simulator.Based on STMicroelectronics CMOS 90nm Technology,this DCO can provide a digitally tuning range from 1GHz to 6GHz with a power dissipation varied from 0.1mW to 3mW.With noise analysis,the phase noise at 10MHz offset frequency is-114dBc/Hz. |
