About Of the Book:

"Design with Operational Amplifiers and Analog Integrated Circuits" is a popular textbook in the field of analog circuit design, written by Sergio Franco. The book provides a comprehensive and practical approach to understanding the theory and design of analog circuits using operational amplifiers (op-amps) and other analog integrated circuits.

The book covers a wide range of topics, including basic op-amp circuits, feedback, stability analysis, frequency response, active filters, oscillators, and many more. The book also includes numerous design examples and practical circuits that illustrate the concepts presented in the text.

The book is widely used as a textbook in undergraduate and graduate courses in electrical engineering and is also popular among practicing engineers in the field of analog circuit design. It is highly recommended for anyone who wants to gain a deep understanding of the theory and design of analog circuits using op-amps and other analog integrated circuits.

Although not explicitly indicated, the book consists of three parts. The first part
(Chapters 1–4) introduces fundamental concepts and applications based on the op-amp as a predominantly ideal device. It is felt that the student needs to develop
sufficient confidence with ideal (or near-ideal) op amp situations before tackling
and assessing the consequences of practical device limitations. Limitations are the
subject of the second part (Chapters 5–8), which covers the topic in more systematic
detail than previous editions. Finally, the third part (Chapters 9–13) exploits the
maturity and judgment developed by the reader in the first two parts to address
a variety of design-oriented applications. Following is a brief chapter-by-chapter
description of the material covered.
Chapter 1 reviews basic amplifier concepts, including negative feedback. Much
emphasis is placed on the loop gain as a gauge of circuit performance. The loop
gain is treated via both two-port analysis and return-ratio analysis, with due attention to similarities as well as differences between the two approaches. The student
is introduced to simple PSpice models, which will become more sophisticated as
we progress through the book. Those instructors who find the loop-gain treatment
overwhelming this early in the book may skip it and return to it at a more suitable
time. Coverage rearrangements of this sort are facilitated by the fact that individual
sections and chapters have been designed to be as independent as possible from each
other; moreover, the end-of-chapter problems are grouped by section.
Chapter 2 deals with I-V, V-I, and I-I converters, along with various instrumentation and transducer amplifiers. The chapter places much emphasis on feedback
topologies and the role of the loop gain T.
Chapter 3 covers first-order filters, audio filters, and popular second-order filters
such as the KRC, multiple-feedback, state-variable, and biquad topologies. The
chapter emphasizes complex-plane systems concepts and concludes with filter
The reader who wants to go deeper into the subject of filters will find Chapter 4
useful. This chapter covers higher-order filter synthesis using both the cascade and
the direct approaches. Moreover, these approaches are presented for both the case
of active RC filters and the case of switched-capacitor (SC) filters.
Chapter 5 addresses input-referrable op amp errors such as VOS, IB, IOS, CMRR,
PSRR, and drift, along with operating limits. The student is introduced to datasheet interpretation, PSpice micromodels, and also to different technologies and
Chapter 6 addresses dynamic limitations in both the frequency and time domains,
and investigates their effect on the resistive circuits and the filters that were studied
in the first part using mainly ideal op amp models. Voltage feedback and current
feedback are compared in detail, and PSpice is used extensively to visualize both
the frequency and transient responses of representative circuit examples. Having
mastered the material of the first four chapters using ideal or nearly ideal op amps,
the student is now in a better position to appreciate and evaluate the consequences
of practical device limitations.
The subject of ac noise, covered in Chapter 7, follows naturally since it combines
the principles learned in both Chapters 5 and 6. Noise calculations and estimation
represent another area in which PSpice proves a most useful tool.
The second part concludes with the subject of stability in Chapter 8. The enhanced coverage of negative feedback has required an extensive revision of frequency
compensation, both internal and external to the op-amp. The fourth edition makes
generous use of the voltage/current injection techniques pioneered by R. D. Middlebrook for loop-gain measurements. Again, PSpice is used profusely to visualize the
effect of the different frequency-compensation techniques presented.
The third part begins with nonlinear applications, which are discussed in
Chapter 9. Here, nonlinear behavior stems from either the lack of feedback (voltage
comparators), or the presence of feedback, but of the positive type (Schmitt triggers),
or the presence of negative feedback, but using nonlinear elements such as diodes
and switches (precision rectifiers, peak detectors, track-and-hold amplifiers).
Chapter 10 covers signal generators, including Wien-bridge and quadrature
oscillators, multivibrators, timers, function generators, and V-F and F-V converters.
Chapter 11 addresses regulation. It starts with voltage references, proceeds to
linear voltage regulators, and concludes with a much-expanded coverage of switching regulators. Great attention is devoted to current control and slope compensation,
along with stability issues such as error-amplifier design and the effect of the right half plane zero in boost converters.
Chapter 12 deals with data conversion. Data-converter specifications are treated
in a systematic fashion, and various applications with multiplying DACs are presented.
The chapter concludes with oversampling-conversion principles and sigma-delta
converters. Much has been written about this subject, so this chapter on necessity
exposes the student only to the fundamentals.
Chapter 13 concludes the book with a variety of nonlinear circuits, such as
log/antilog amplifiers, analog multipliers, and operational transconductance amplifiers with brief exposure to gm-C filters. The chapter culminates with an introduction to phase-locked loops, a subject that combines important materials addressed
at various points in the preceding chapters.
