Does the profile of phase-noise power spectrum density (PSD) vary with time?

I will promptly provide any detail or revise my question aimed at any feedback. Does the profile of phase-noise power spectrum density (PSD) vary with time? The conclusion may be that it won’t ...

Two details about phase noise have been confusing me for a long time. Hope to be resolved

Just like FLOYD M. GARDNER said in the PhaseLock Techniques, 3rd Edition: "In light of that success in spectrum analyzers, a practitioner’s answer to the question above is: The spectrum of phase noise ...

Can phase noise be averaged out?

I have an ADC sampling a downconverted RF signal at fs. I obtain N=2^15 samples of the RF input signal "fcarrier + fs/10". The more I average, the more the entire noise floor shifts down (as expected,...

Phase noise reduction in LC oscillator with a high-loss capacitor

I`ve got a capacitive vibration probe whose base capacitance may vary from 4 to 10 pF due to manufacturing/installation tolerances, whereas vibrations it detects can only alter its capacitance in sub-...

A capacitor as loop filter of a DLL

I know that if a second order, type two PLL has only a capacitor as its loop filter, it is unstable because its phase margin would be zero. but why is it ok for a DLL to only have a capacitor as its ...

Error with phase noise to jitter calculation

I'm trying to get the jitter for an oscillator. The nominal frequency \$f_0\$ is 10 MHz, I'm integrating from 1 Hz to 100 kHz. The specifications are given as "RF Output Phase Noise (SSB)", in dBc/Hz. ...
