SPECTRE18.1: Crystal Oscillator Simulation using SpectreRF
Crystal Oscillator is one of the class of oscillators which brings its own challenges tosimulate. One of the key challenges it brings to simulate is a long startup time.The purpose of this document is to make suggestions regarding the best practices forsimulating Crystal Oscillators. A database composed of the circuits needed toreproduce these results is provided separately.This RAK demonstrates a method to do Crystal Oscillator simulation using SpectreRFAnalyses. Initially, a transient analysis is done and then hb/hbnoise analysis is used todetermine the oscillation frequency and the phase noise of the oscillator.
