A general method to simulate noise in oscillators based on frequency domain techniques

摘要

An approach using perturbation theory to simulate the noise behavior of free-running microwave oscillators based on a piecewise harmonic balance technique is outlined and applied to a planar integrated microwave oscillator at 14 GHz. A single-sideband phase noise of -90 dBc/Hz at an offset frequency of 100 kHz was measured. Simulated and measured single-sideband phase noise values agree within the accuracy of measurements.
