The noise result is connected with the duty cycle and the bias point (AF,
KF spice values ). We took the time to recalculate the Parzen and Frerking
examples and they do not give the best possible answer.We were able to
make the oscillators much better .
If you look at the world leading Wenzel product line they got about 20 db
better in the last 10 years (less phase noise) as they replace these
published approximation with our correct mathematical solutions and better
test equipment. We are moving towards 100 Ghz and better phase noise.
That's something that has been bothering me lately: Most of your
publications are about the noise in UHF and GHz applications, hardly
any for the area where most of time metrology happens: at 10MHz and 100MHz.
Is this because the sub-100MHz range oscillators are a solved problem
and hit the physical limits of what noise optimization can do? Or is
it because there is more money to be made in the >100MHz range?

Moin,
I'm quoting the mail in full, because it seems to have not made it to
the mailinglist due to its large attachment.
I uploaded the attachment to my server, you can find it here:
