BSIMSOI MOSFET Model (bsimsoi)

---

The BSIMSOI model is a Silicon-on-Insulator (SOI) MOSFET model. It was developed by the BSIM/SOI modeling group at the University of California, Berkeley.

There are two modes in BSIMSOI depending on the value of soiMod:

• PD mode (soiMod=0), where the body potential is independent of ΔV_bi (V_BS>ΔV_bi). Hence the calculation of ΔV_bi is skipped in this mode.
• DD (Unified) mode (soiMod=1), where both ΔV_bi and body current/charge are calculated to capture the floating-body behavior exhibited in FD devices.
• FD mode (soiMod=2), where the body potential is equal to ΔV_bi. Hence the calculation of body current/charge, which is essential to the PD model, is skipped.
