Are there references to some practical circuits? That would be great.

A google search on "injection locking" and "synchronous oscillator"
results in a lot of conceptual descriptions but nothing that one can build,
try out and study. Maybe some of the scientific articles or books contain
circuits, but I am not a IEEE member.
