Here's a new article, on IEEE's site (and this one's free):

"Oscillator Phase Noise: A 50-Year Review", by David B. Leeson
http://ieeexplore.ieee.org/stamp/stamp.jsp?arnumber=7464875

Also, a few months IEEE had a "Special Issue to celebrate the 50th anniversary of the Allan Variance".
The full list of papers is here:
http://ieeexplore.ieee.org/xpl/tocresult.jsp?isnumber=7445917

Most of the articles are behind the IEEE paywall. Some free exceptions here:

"Introduction to the Special Issue on Celebrating the 50th Anniversary of the Allan Variance"
http://ieeexplore.ieee.org/stamp/stamp.jsp?arnumber=7445935

"The Parabolic Variance (PVAR): A Wavelet Variance Based on the Least-Square Fit"
http://ieeexplore.ieee.org/stamp/stamp.jsp?arnumber=7323846
also at:
http://arxiv.org/pdf/1506.00687.pdf

"Simulations of the Hadamard Variance: Probability Distributions and Confidence Intervals"
http://ieeexplore.ieee.org/stamp/stamp.jsp?arnumber=7350241

Best of all, a free version of the David Allan and Judah Levine paper is here:

"A Historical Perspective on the Development of the Allan Variances and Their Strengths and Weaknesses"
http://tf.boulder.nist.gov/general/pdf/2834.pdf

It has always irked me that no credit was given to Edson's
pioneering 1953 book "Vacuum tube oscillators" in Leeson's papers
and I see that the omission continues in the latest paper. You can see
from the following reference that Edson was the true pioneer in this
field:

http://garfield.library.upenn.edu/classics1983/A1983QV00800001.pdf

He actually had the basic idea in 1934. He is the proverbial
"unsung hero".

Hardly unsung. Harvard PhD Sigma Xi as a Gordon McKay Scholar,
distinguished career at Bell Labs, Illinois Institute of Technology,
Bell Labs Radio Research Laboratory, Georgia Institute of Technology,
Georgia Tech Research Institute, Stanford (working with Fred Terman, as
he had at RRL), Stanford Electronics Research Laboratory, GE, founded
Emtech, Stanford Research Institute, IEEE Life Fellow.

Edson was very well-known and well-respected in his day, but he didn't
publish much.

To this day, I still refer to "Vacuum-Tube Oscillators" regularly --
over 60 years since it was published!

Best regards,

Charles

Then write an article and point it out. Have a discussion with David
Leeson for that mather, he is still active enough.

It could be that Edson's work was not known to them in this context.

Regardless, just put it in text and show the precursor work. I bet that
many does not know of this work precursor the Leeson 1966 paper.

You have this knowledge, share it in proper ways.

Cheers,
Magnus
