Abstract :
This paper describes an experimental technique for rapidly finding the boundaries of Arnold tongues. The method is suitable for characterizing the locking regions of injection-locked frequency dividers. The algorithm is described and examples are presented to demonstrate the value of the technique in comparing divider architectures with tail and direct injection.
