Abstract :
The influence of a small but nonzero resonant overtone of the drive-signal on the static and dynamic characteristics of subharmonic injection-locked oscillators is investigated by means of a perturbation based phasor-domain approach. Both theoretical and computer simulation results show that, if certain conditions on the circuit parameters occur, even a very small amplitude overtone (e.g., -60 dBc) significantly affects the system behaviour. This fact may explain the discrepancies sometimes observed between experiments and predictions based on previous analysis methods
