A new method for the analysis of sinusoidal oscillators, based on a general characterization of feedback electronic systems, is drawn. This exact and algorithmic method allows us to find the oscillation conditions by the calculation of only one transfer function of a circuit which, generally, is obtained by a simple inspection of the system.
