基本説明
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. Supported by over 500 equations and 130 illustrations.
Full Description
Heterojunction bipolar transistors (HBTs) are a quite young technology and this book aims not only to give a reference of relevant HBT models, but also to discuss their background from a circuit-designer's point of view.
