摘要
本文提出了一种新颖的LC振荡器拓扑结构，它比其他LC振荡器需要更低的启动最小功率。本文介绍的gm增强LC振荡器拓扑结构可以在0.18 μ m CMOS工艺中将启动振荡所需的功率降低35%，而与标准LC振荡器相比，相位噪声水平没有明显降低。这种振荡器可用于低功率、低噪声通信收发器。
This paper presents a novel LC oscillator topology that requires lower minimum power for startup than other LC oscillators. The Gm-boosted LC oscillator topology introduced here can drop the power required to start an oscillation by 35% in a 0.18 mum CMOS process, without significant degradation in phase noise levels compared to a standard LC oscillator. Such an oscillator may be useful in low power, low noise communication transceivers.
