[sdiy] LTSpice macromodell help

[Phil Macphail]

If LTspice can handle behavioral expressions, then tanh will give you the limiting function you require. I don't know this flavour of Spice, but it is my preferred method of building ideal components that converge well and don't wander to silly node voltages,
