摘要：
This paper aims at presenting an equation describing a relation between power consumption and phase noise of the widely used CMOS cross-coupled LC differential oscillator. This equation is derived by using periodic time-varying method and it relates oscillator's key performance parameters, e.g., oscillation frequency and amplitude, sideband spectrum and bias current, and CMOS process parameters. The validity of the proposed equation was confirmed by the periodic noise simulation available in the Cadence's Virtuoso Spectre Circuit Simulator.
