BSIM3SOI Version 2.1 (FD, DD and PD)
Models Released in SmartSpice

Introduction

The Berkeley BSIM3SOI version 2.1 models, released in September 1999, have been implemented in SmartSpice. The three new models are selected according to LEVEL selector.

• • LEVEL = 26 selects the BSIM3SOI2FD (Fully depleted) model

• • LEVEL = 27 selects the BSIM3SOI2DD (Dynamic depletion) model

• LEVEL = 29 selects the BSIM3SOI2PD (Partially depleted) model

The SmartSpice implementation of the three models is close but not identical to the UC Berkeley releases. The SmartSpice implementation provides a number of improvements and additional parameters currently unsupported in Berkeley’s BSIM3SOIv2 models.
