  • Abstract
    In spite of assumptions to the contrary, charge-pump phase-lock loops (CPPLL) with a phase-and-frequency detector can, in practice, stay in false lock, in the case of certain electronic implementations. False-lock sources are analysed for a CPPLL with a passive filter, and as a result design rules are given to prevent CPPLLs from false locking.
