Abstract :
A novel large signal periodic steady state algorithm, capable of simulating resonant oscillators, has been used to generate a relationship between the internal free energy and running frequency of a simple Colpitts oscillator. From this relationship, assuming thermal equilibrium, Boltzmann statistics can be applied to yield the probability of finding the oscillator running at any given frequency. Prediction of phase noise from fundamental circuit and device properties then becomes a possibility
