Description
Master powerful GaAs HBT modeling techniques with this comprehensive, one-stop resource. The book helps you gain total command of heterojunction bipolar transistor (HBT) models by offering insight into compact HBT modeling strategies from a circuit-designers point of view. It provides you with detailed coverage of state-of-the-art tools that help you select the best model to meet specific design requirements, know what physical effects to expect, and modify or create new models to optimize simulation accuracy and to enhance the chance of achieving single-pass success in circuit design. Supported by over 500 equations and 130 illustrations, the book offers full documentation and guidance to deploy HBT models ranging from Gummel-Poon and VBIC, to UCSD, Agilent, and FBH models. Small-signal, large-signal and noise modeling, and measurement and parameter extraction strategies are discussed in detail with regard to the respective models, and expert commentary at every step provides real-world insight in explaining, for example, why a model doesn't yield the expected results or how to modify an existing model properly. Emphasizing how toù procedures without getting bogged down in device physics, this indispensable book puts the full power of active device modeling and circuit simulation at your command.
