Point taken. No offense was intended.

Touche'.

I understand this to be true, but my original mention of pole
splitting was to indicate that designer's like yourself take
the time to mathematically model your control system and provide,
essentially, solid compensation which improves the system behavior.
A lot of the high-performance op amps you mention target specific
needs in the customers application, and you guys often provide
sufficient documentation, spice models etc. to use them effectively.

I agree with you that this thread has strayed too far from
the list's subject matter.  You guys have piqued my interest to
investigate the uses of fuzzy logic.
