A new method for jitter decomposition through its distribution tail fitting

media, reflections, cross-talk, electromagnetic interference (EMI), systematical modulations, and pattern dependency, for DJ; and thermal noise, shot noise, flick noise, random modulation, non-stationary interference, for RJ. In the real world applications, what is measured, in general, is the total jitter, namely both DJ and RJ are mixed together. To understand the root cause of the jitter, separating and identifying each jitter component is essential. As the speed for microprocessor, memory, data bus, and transmission media increases steadily, if not exponentially, failures caused by jitter will become more and more severe. Therefore, how to model, simulate, measure, and characterize jitter will become even more important and challenging for high-speed signals in the forth coming years.
