.ChaoticCircuits.Components.ZenerDiodePairApproximation .ChaoticCircuits.Components.ZenerDiodePairApproximationThis is an approximation for a Zener diode pair as described in [Lueck1995] .
If voltage v is prescribed, the current i can be unambiguously determined.
If current i is prescribed, between v = -V_bt and v = +V_bt there is a manifold of solutions for the voltage v.
