MOSFET Modeling & BSIM3 User’s Guide


Book Description

Circuit simulation is essential in integrated circuit design, and the accuracy of circuit simulation depends on the accuracy of the transistor model. BSIM3v3 (BSIM for Berkeley Short-channel IGFET Model) has been selected as the first MOSFET model for standardization by the Compact Model Council, a consortium of leading companies in semiconductor and design tools. In the next few years, many fabless and integrated semiconductor companies are expected to switch from dozens of other MOSFET models to BSIM3. This will require many device engineers and most circuit designers to learn the basics of BSIM3. MOSFET Modeling & BSIM3 User's Guide explains the detailed physical effects that are important in modeling MOSFETs, and presents the derivations of compact model expressions so that users can understand the physical meaning of the model equations and parameters. It is the first book devoted to BSIM3. It treats the BSIM3 model in detail as used in digital, analog and RF circuit design. It covers the complete set of models, i.e., I-V model, capacitance model, noise model, parasitics model, substrate current model, temperature effect model and non quasi-static model. MOSFET Modeling & BSIM3 User's Guide not only addresses the device modeling issues but also provides a user's guide to the device or circuit design engineers who use the BSIM3 model in digital/analog circuit design, RF modeling, statistical modeling, and technology prediction. This book is written for circuit designers and device engineers, as well as device scientists worldwide. It is also suitable as a reference for graduate courses and courses in circuit design or device modelling. Furthermore, it can be used as a textbook for industry courses devoted to BSIM3. MOSFET Modeling & BSIM3 User's Guide is comprehensive and practical. It is balanced between the background information and advanced discussion of BSIM3. It is helpful to experts and students alike.




BSIM-Bulk MOSFET Model for IC Design - Digital, Analog, RF and High-Voltage


Book Description

BSIM-Bulk MOSFET Model for IC Design - Digital, Analog, RF and High-Voltage provides in-depth knowledge of the internal operation of the model. The authors not only discuss the fundamental core of the model, but also provide details of the recent developments and new real-device effect models. In addition, the book covers the parameter extraction procedures, addressing geometrical scaling, temperatures, and more. There is also a dedicated chapter on extensive quality testing procedures and experimental results. This book discusses every aspect of the model in detail, and hence will be of significant use for the industry and academia. Those working in the semiconductor industry often run into a variety of problems like model non-convergence or non-physical simulation results. This is largely due to a limited understanding of the internal operations of the model as literature and technical manuals are insufficient. This also creates huge difficulty in developing their own IP models. Similarly, circuit designers and researcher across the globe need to know new features available to them so that the circuits can be more efficiently designed. - Reviews the latest advances in fabrication methods for metal chalcogenide-based biosensors - Discusses the parameters of biosensor devices to aid in materials selection - Provides readers with a look at the chemical and physical properties of reactive metals, noble metals, transition metals chalcogenides and their connection to biosensor device performance

MOSFET Models for SPICE Simulation


Book Description

An expert guide to understanding and making optimum use of BSIM Used by more chip designers worldwide than any other comparable model, the Berkeley Short-Channel IGFET Model (BSIM) has, over the past few years, established itself as the de facto standard MOSFET SPICE model for circuit simulation and CMOS technology development. Yet, until now, there have been no independent expert guides or tutorials to supplement the various BSIM manuals currently available. Written by a noted expert in the field, this book fills that gap in the literature by providing a comprehensive guide to understanding and making optimal use of BSIM3 and BSIM4. Drawing upon his extensive experience designing with BSIM, William Liu provides a brief history of the model, discusses the various advantages of BSIM over other models, and explores the reasons why BSIM3 has been adopted by the majority of circuit manufacturers. He then provides engineers with the detailed practical information and guidance they need to master all of BSIM's features. He: Summarizes key BSIM3 components Represents the BSIM3 model with equivalent circuits for various operating conditions Provides a comprehensive glossary of modeling terminology Lists alphabetically BSIM3 parameters along with their meanings and relevant equations Explores BSIM3's flaws and provides improvement suggestions Describes all of BSIM4's improvements and new features Provides useful SPICE files, which are available online at the Wiley ftp site
