Abstract

The output phase noise of a fractional-N frequency synthesizer comprises two components: intrinsic noise in the controlled oscillator itself, and extrinsic noise caused by unwanted modulation at its control input. The extrinsic noise contains both stochastic and deterministic components. This paper considers strategies to minimize the extrinsic noise component by addressing deterministic nonlinear dynamical mechanisms.
