这项工作提出了测量数据和分析,准确地比较三,四级环形振荡器。这里考虑的延迟单元拓扑结构包括线性源耦合和两种饱和类型。每个振荡器是同时制作在一个1.8 V,0.18 /spl μ/m CMOS工艺,其特征在于相位噪声,功耗和调谐范围。
This work presents measured data and analysis, accurately comparing three, four-stage ring oscillators. The delay cell topologies considered here include the linear source coupled, and two saturating types. Each oscillator is fabricated concurrently in a 1.8 V, 0.18 /spl mu/m CMOS process and is characterized for phase noise, power consumption and tuning range.
