OpAmp Output DeadBand

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...
