Hi all,
1- The psd plot of a VCO output (simulated) shows two kinds of spurs.
Spurs appears:
Aroud the carrier frequency fc
At the frequency 2fc, 3fc ...etc
What are the causes of these spurs and How to eliminate each kind ?
2- The carrier frequency of the VCO is 4G the figure bellow shows the obtained psd and the wanted psd plot.
Actually another simulation showed that when fc=4.3G the spurs appears only at 2fc, 3fc etc...
Do you know why ?
All your comments are welcomed !
Thanks in advance.
