(E-BOOK Teknik Mesin) ANALYSIS AND DESIGN OF ANALOG INTEGRATED CIRCUITS
In the 23 years since the publication of the first edition of this book, the field df analog
integrated circuits has developed and matured. The initial groundwork was laid in bipolar
technology, followed by a rapid evolution of MOS analog integrated circuits. Furthermore,
BiCMOS technology (incorporating both bipolar and CMOS devices on one chip)
has emerged as a serious contender to the original technologies. A key issue is that CMOS
technologies have become dominant in building digital circuits because CMOS digital
circuits are smaller and dissipate less power than their bipolar counterparts. To reduce
system cost and power dissipation, analog and digital circuits are now often integrated
together, providing a strong economic incentive to use CMOS-compatible analog circuits.
As a result, an important question in many applications is whether to use pure CMOS or a
BiCMOS technology. Although somewhat more expensive to fabricate, BiCMOS allows
the designer to use both bipolar and MOS devices to their best advantage, and also allows
innovative combinations of the characteristics of both devices. In addition, BiCMOS
can reduce the design time by allowing direct use of many existing cells in realizing a
given analog circuit function.
