SPICE3 Junction Diode Model

There are two junction models in the BSIM3v3 device model. The diomod parameter determines the model to be used in a given simulation:

• If diomod=1 (default value), the model uses the equations described in the chapter Common MOSFET Equations.
• If diomod=0, the model uses the equations described in Chapter 9 of the BSIM3v3.2.2 MOSFET Model-Users’ Manual available at:
  http://www-device.EECS.Berkeley.EDU/~bsim3/get.html
  The BSIM3v3 device model uses the same equations when tlev=1.

Starting with MMSIM1211ISR17, bsim3v3 supports the trap-assisted tunneling current, if diomod!=100. For more information, refer to the equations described in the Total Junction Source/Drain Diode Including Tunneling section in chapter BSIM4 Level-14 Model (bsim4).
