FDSOI technology and innovative circuit design based on this technology offers several advantages over conventional MOSFETs. These advantages come with unique challenges. Operation and modelling of these devices are complex due to two independent controlling inputs. Industry standard FDSOI compact model BSIM-IMG for IC design helps readers develop an understanding of the complexity of FDSOI device operation and its simulation model.This book begins with the physics and operation of the FDSOI device explaining not only how FDSOI enables further scaling but also how it offers new unique possibilities in circuits. Following chapters cover in-depth details of the industry standard compact model BSIM-IMG for FDSOI devices.The books addresses the core surface-potential calculations and the plethora of real devices effects included in this accurate simulation model. The authors include chapters on step-by-step parameters extraction procedure for BSIM-IMG model and rigorous industry grade tests that the BSIM-IMG model has undergone. There is also a chapter on analog and RF circuit design in FDSOI technology using the BSIM-IMG model.This book, written by the original developers of the industrial standard model, serves as excellent reference for the new BSIM-IMG compact model for emerging FDSOI technology.
