PLL Performance
What does not cause reference spurs?
Leakage current from the charge pump
Mismatch current of the charge pump
Thermal noise currents produced from the charge pump
All of these cause reference spurs
The frequency for which the open loop gain equals 1 ("corner frequency")is called?
Filter Pole
Filter Pole
Loop Bandwidth
Cut-off frequency
If the phase noise is increased by 6dB across the integration bandwidth and there are no spurs, what is the impact in RMS phase error?
RMS phase error is half of what it was before
RMS phase error is unaffected
RMS phase error is increased by a factor of square root of 2
RMS phase error is doubled
