Abstract
Embodiments may include methods, systems, and computer-readable storage mediums that may be used to simulate phase noise for an oscillator circuit. In some embodiments, a method of simulating phase noise for an oscillator circuit may include providing an oscillator circuit description. A time-domain representation of a small signal phase noise of the oscillator circuit description may be determined. A shooting Newton matrix representation of the time-domain representation of the small signal phase noise may be generated. The shooting Newton matrix representation may be augmented to include a phase-shift factor and a pinning equation. The augmented shooting Newton matrix representation may be solved to determine a signal output of the oscillator circuit.
