摘要

提出了一种采用UMC 0.18μm工艺设计的新型低相位噪声压控环形振荡器。提出的设计包含9级差分延迟单元,具有多通环路结构。线性频率-电压特性在很宽的调谐范围内表现出来。九级环形振荡器的调谐范围为1.1-2.3 GHz。在中心频率为1.8 GHz的偏移1MHz时,估计相位噪声为-108.13dBc/Hz。该设计使用1.8V电源,工作在1.8GHz时最大功率为65mW。

A low phase noise CMOS voltage-controlled differential ring oscillator
The paper presents a novel low phase noise voltage-controlled ring oscillator designed in UMC 0.18μm technology. The proposed design contains nine stages of differential delay cells with multiple-pass loop architecture. Linear frequency - voltage characteristics are exhibited over a wide tuning range. The tuning range of nine-stage ring oscillator is 1.1-2.3 GHz. A phase noise of -108.13dBc/Hz was estimated at an offset of 1MHz from a center frequency of 1.8 GHz. The design uses a 1.8V supply and consumes a maximum power of 65mW while operating at 1.8GHz.
