Implementation Details

For V≤VTH

f(V)=0.0

For V>VTH

where

NOTES:

  1. SC is a scale factor that scales the parameters as if it were a FET.

  2. R1 and R2 are scaled inversely with SC.

  3. TAU is a constant time delay.

  4. The model does not ensure that dI/dV is continuous at VTH. The user should select polynomial coefficients to guarantee this.
