Hi, Ken,
    I got a question regarding your application note: Predicting the Phase Noise and Jitter of PLL-Based Frequency Synthesizers
Ken Kundert (Designer’s Guide Consulting, Inc.).
    On page 25, you mention about Metrics are unbounded with presence of flicker noise. Could I know what unbounded means?  

Refer your application:
"
Cycle-to-cycle jitter is a metric designed to identify large adjacent cycle displacements.
It is like edge-to-edge jitter in that it is a scalar jitter metric that does not contain information
about the correlation in the jitter between distant transitions. However, it differs
in that it is a measure of short-term jitter that is relatively insensitive to long-term jitter
[13]. As such, cycle-to-cycle jitter is the only jitter metric that is suitable for use when
flicker noise is present. All other metrics are unbounded in the presence of flicker noise

"

  Does that mean when we use edge to edge Jitter, Jitter  is not accurate or at least under some condition is not accurate? Could we trust the simulation result?

Thanks!

Paulin

Why would 1/f noise impact cycle-cycle (adjacent cycle) jitter? Flicker noise is a fractional integrated Brownian walk, so I expect that the total distance of the sailor from the bar shouldn't vary significantly between two steps.

Can someone help me understand this better?
