1 Random Jitter

Random jitter is an ever present phenomenon that cannot always be predicted. The random jitter experienced by a device is a combination of multiple factors, including thermal noise, trace width variations, shot noise, flicker, etc. Random jitter is a broadband stochastic Gaussian process that is sometimes referred to as intrinsic noise because it is always present. Random jitter has a normal probability distribution function (PDF) that is unbounded and cannot maintain a well-defined peak-to-peak value. Instead it is commonly described by its standard deviation. Random jitter is also independent from other sources of jitter, in that its presence does not magnify the effects of other sources of jitter.
