FREQUENCY DRIFT DETECTOR, COMMUNICATION UNIT AND METHOD THEREFOR

A frequency drift detector includes a frequency-to-voltage converter, FVC, arranged to receive a reference frequency signal and configured to generate an FVC output voltage. The frequency drift detector also includes a voltage regulator arranged to output at least one regulated voltage; and a voltag...

Beschreibung
Zusammenfassung:	A frequency drift detector includes a frequency-to-voltage converter, FVC, arranged to receive a reference frequency signal and configured to generate an FVC output voltage. The frequency drift detector also includes a voltage regulator arranged to output at least one regulated voltage; and a voltage comparator coupled to an output of the FVC and an output of the voltage regulator. The voltage comparator is arranged to compare the FVC output voltage and the at least one regulated voltage and generate an error signal in response to determining that the FVC output voltage exceeds a frequency drift level indicated by the at least one regulated voltage.
