Hi,
I’m reading materials about VCO design for reference, and in one of them there is something I can’t understand:
“Substituting this result gives Cv = 675fF. Because the varactor is in series with a 5pF AC coupling MIM capacitor, its actual value should beincreased to about 790fF.”
Why exactly we should increase the value of Cv?
Thank you!
