Well, certain circuits rely on effects that may just work with small
signals, like a transistor is only linear in a small operating area.
Same goes for a FET or an OTA. So demanding 'perfect' designs is not 
realistic. The world of electronics simply isn't perfect.

S&H's a module and s&h's looking good
