OT: Equation Solving

Started by Jim Thompson June 11, 2016
In my development of a generalized OpAmp model with independent
setting of GBW, Slew Rate and Input Transition Width I found myself
hung on solving the transfer function shown in green...


for the value of VB at the right-most zero crossing.

My in-PSpice Newton Solver barfed.

Then I lit on the idea of using my new Most_Positive segment splicer
(*) to produce the function in red.

Wrapped an ideal OpAmp around it and it spits out the proper VB value.

(*) Smooth fitting, all derivatives present, finite and continuous.
