Signal Integrity Tips

Party school? Liberal Arts college? State School? How are your colleagues** faring? In a yearlong effort, PayScale, an online provider of global compensation data, surveyed 1.2 million graduates, with a median of 15.5 years of work experience, from more than 300 U.S. schools. You can either believe the pay comparison of Catbert the Evil Director [...]

IBIS (Input/Output Buffer Information Specification) is a behavioral modeling specification for characterizing the inputs and outputs of integrated circuits. This 7 minute video shows how to use them in a signal integrity workflow. The ADS Transient-Convolution Simulator is used to determine the eye diagram and jitter decomposition from a schematic that includes IBIS models from [...]

How fast do the electrons travel in copper? Not as fast as you might think. A tortoise is much quicker. The drift velocity at a safe current density (say 1A/mm2) is ~0.08mm/s, so slow you might wonder how a wall switch is able to turn the ceiling light on, never mind a how multigigabit/s serial link [...]
