Aaargh! I just loooove flicker noise [Open Column]

The author discusses his love-hate relationship with flicker noise and the fact that there is still a lot we don´t know about it and might want to find out. For one, it is still not agreed what the best mathematical model is, and he has not yet found a mathematical model that both includes the non-stationarity of 1/f noise and is also useful for designers. On the to-do list are also better ways to calculate and simulate it; things like auto-zeroing, correlated double sampling and other switched circuits are really cumbersome to analyze and to simulate in IC design tools (if it can be done at all). We also should creatively use Klumperink´s and Bloom´s switching ideas to reduce the effect of flicker noise in many different ways. The fourth missing element is teaching; flicker noise is so omni-present and important, but he has yet to find a university graduate who knows more about it than that it´s there (and in most cases not even this). These are all things that could be contributed by the members of the IEEE CAS society.
