Cmos Analog Circuit Design — allen holberg free download of the book

The evolution of very large scale integration (VLSI) technology has developed to the
point where millions of transistors can be integrated on a single die or “chip.” Where
integrated circuits once filled the role of sub-system components, partitioned at analog-digital
boundaries, they now integrate complete systems on a chip by combining both
analog and digital functions [1]. Complementary metal-oxide semiconductor (CMOS)
technology has been the mainstay in mixed-signal
implementations because it provides
density and power savings on the digital side, and a good mix of components for analog
design. By reason of its wide-spread use, CMOS technology is the subject of this text.
Due in part to the regularity and granularity of digital circuits, computer aided design
(CAD) methodologies have been very successful in automating the design of digital
systems given a behavioral description of the function desired. Such is not the case for
analog circuit design. Analog design still requires a “hands on” design approach in
general. Moreover, many of the design techniques used for discrete analog circuits are not
applicable to the design of analog/mixed-signal VLSI circuits. It is necessary to examine
closely the design process of analog circuits and to identify those principles that will
increase design productivity and the designer’s chances for success. Thus, this book
provides a hierarchical organization of the subject of analog integrated-circuit design and
identification of its general principles.
