Aimed primarily for undergraduate students pursuing courses in VLSI design, the book emphasizes the physical understanding of underlying principles of the subject. It not only focuses on circuit design process obeying VLSI rules but also on technological aspects of Fabrication. VHDL modeling is discussed as the design engineer is expected to have good knowledge of it. Various Modeling issues of VLSI devices are focused which includes necessary device physics to the required level. With such an in-depth coverage and practical approach practising engineers can also use this as ready reference. Key features: Numerous practical examples. Questions with solutions that reflect the common doubts a beginner encounters. Device Fabrication Technology. Testing of CMOS device BiCMOS Technological issues. Industry trends. Emphasis on VHDL.
