Linearized digital phase and frequency detector

摘要: A digital phase and frequency detector is capable of providing a linearized transfer function. The includes two latches each receiving an input output. output the combined by logic gate to generate reset signal. linearization result delay signal used within comparator. This improved comparator eliminates non-linearities which would otherwise be inherent in its function thereby degrade performance phase-locked systems employing easily manufactured as integrated circuit does not require any external signals order eliminate non-linear region.
