Abstract

The paper documents the development of a novel time-domain model of injection-locked oscillator phase-noise response. The methodology follows a first-principle approach and applies to all circuit topologies, coupling configurations, parameter dependencies etc. The corresponding numerical algorithm is readily integrated into all major commercial simulation software suites. The model advances current state-of-the-art pertaining to analytical modelling of this class of circuits. Using this novel analytical framework, several important new insights are revealed which, in-turn, translate into useful design rules for synthesis of injection-locked oscillator circuits with optimal noise performance.
