摘要
When the oscillators are coupled, coupling methods are very important and influence some factors, for example, increasing or decreasing of noise and whether multi-phase synchronization phenomena can be observed or not due to the number of oscillators and so on. In this paper, multi-phase synchronization phenomena which are generated in RF CMOS LC oscillators with mutual inductor couplings and the stability of various oscillatory modes in the proposed model are investigated. In the proposed system, multi-phase synchronization phenomena can be observed regardless of the number of oscillators in RF region due to setting up the sign of the mutual inductance properly, and the each oscillatory mode is stable.
