Turns out I was making things too difficult with my nice LOG(COSH(x)) "smoother" when it comes to modeling OpAmp Output DeadBand.



Examination of the LOG(COSH(x)) solution puzzled me, exhibiting some unexpected instability.



Last night, as I tossed and tumbled, fearing a Clinton Supreme Court disaster when I awoke, one nightmare suggested this downright trivial solution...

Why not just use transistors in an opamp model? That would be more accurate... get the impedance changes right, too.

That's only a small piece of the puzzle. My object is always to make models that converge and behave like the real-deal. ...Jim Thompson
