A design approach for integrated CMOS LC-tank oscillators using bifurcation analysis

[摘要] Electrical oscillators play a decisive role in integratedtransceivers for wired and wireless communication systems. In thiscontext the study of fully integrated differential VCOs has receivedattention. In this paper formulas for investigations of thestability as well as the amplitude of CMOS LC tank oscillators arederived, where an overall model of nonlinear gain elements is used.By means of these results we are able to present an improved designapproach which gives a deeper insight into the functionality of LCtank VCOs.
