Аннотация

We address the relationship between voltage noise at the input of a threshold comparator and random changes in the timing of the comparator output toggle timing (jitter). Models that go beyond the na¨ıve linear relationship are presented and shown to match experiment. They help reconcile predictions with verifiable device performance; more over, they allow an approximate measurement of the noise bandwidth without the help of high-frequency equipment. In the course our investigation, a PC/laptop toolset was constructed that lets a neophyte study noise via jitter. This toolset can also be used in education to teach the notion that a biased view of a random phenomenon can arise from triggering on the tails of its distribution.
