Design with Operational Amplifiers and Analog Integrated Circuits

Franco’s “Design with Operational Amplifiers and Analog Integrated Circuits, 3e” is intended for a design-oriented course in applications with operational amplifiers and analog ICs. It also serves as a comprehensive reference for practicing engineers.

This new edition includes enhanced pedagogy (additional problems, more in-depth coverage of negative feedback, more effective layout), updated technology (current-feedback and folded-cascode amplifiers, and low-voltage amplifiers), and increased topical coverage (current-feedback amplifiers, switching regulators and phase-locked loops).

  • This is a great book, it contains most of what you need to know about operational amplifiers, starting from the basics to the inner workings of the device. May I say that probably what I find most appealing about this book are the “end of chapter” problems?, perhaps the best approach to end of chapter problems I’ve ever encountered in an electronics textbook, let me elaborate on that: Instead of just being mere academic circuits with no use, starting from chapter 1 you will find a great deal of useful real-life circuits, the author may ask you to derive the gain equation of the circuit or to prove circuit operation, or any other parameter, which in turn, help you understand how real life circuits work, or maybe even use the circuit you just solved in a real application. I guess that what im trying to say is that even if you will find basic drill excercises, you will also find problems which wont stay only on paper.
    The book is somewhat pricey and the reason I gave it 4 stars rather than 5 is that on several occasions the author will just flash formulae at you with the tinniest ammount of information about where did all come from, I understand that the book would have been much thicker if every little nuance had to be written, but this forces you to constantly prove every equation, which is a good thing, however simple things that could be easily understood with a little more information become complicated and force you to spend several minutes trying to figure out how the author got to the formula. I make several notes at the bottom of the pages to save myself a lot of time if I ever have to go back and re-read a particular section.
    That being said, the material is very well presented, and overall this is a must-have book for every EE interested on analog design.
  • I found Franco’s work to be as enthralling to read as it was complete and deep in coverage. Not since the immortal Huelsman and Allen (a work long ago “overcome by events”) has such a titanic writing job been undertaken in the field of linear circuit and analog filter design. I would stop short of saying–as one reviewer did–that the book says “everything you could possibly want to know about analog design.” (I certainly don’t recall having seen Miller’s theorem or the hybrid-pi model–nor did I expect to!). Unfortunately, the book still leaves one puzzle unanswered: does it really matter which input carries the “+” sign and which carries the “-” sign? (The answer is no: it’s merely convention that an inverting/noninverting network attaches the source to the “-“/”+” terminal.) Bravo, Dr. Franco. This is a treasured addition to my library, even at $110.
  • This book is great for the upper division undergraduate and the graduate student alike. The author writes clearly and prioritizes getting his point across above elegant writing which I appreciate in an engineering text. Too often in engineering textbooks authors prefer elegance over simplicity, which is fine, but not if it gets in the way of getting the point across.
    The example problems are phenomenal. The author uses just enough examples, placed at exactly the right points in the text, that drive home the important concepts from each section. If you read through this book and work the example problems as you go along, you’ll have no problem understanding the material. This book makes electronics simple.
  • Mulling through some old reviews, I noticed that I left a technical error (more of a technical glossing-over) in my review of Franco’s opus. It’s high time I corrected it, since it’s been there for more than a year, no doubt befuddling readers who thought they knew something about analog electronics. Specifically, I had said that the designation of the input terminals as ‘+’ and ‘-‘ really made no difference: it’s more reflective of convention, sciz. (assuming something other than a difference amplifier), the significant input network is attached to ‘-‘–with ‘+’ grounded–if the configuration is inverting, but to ‘+’ (with ‘-‘ grounded) if the configuration is non-inverting. That’s the truth, but it isn’t the whole truth. When we examine border cases–those that tax the operational limits of the device, straying outside the “passband,” analogically speaking (yes, I know, that typically refers to a frequency range, but here I use it to address an input voltage difference range)–the otherwise cosmetic or mnemonic choice of ‘+’ or ‘-‘ terminal becomes rather more manifest. Remember that the amplifier actually amplifies the input voltage difference in the microscopic sense–even though it implements a semantically notable linear operation in the macroscopic sense–relying upon the feedback network to remanufacture an appropriate input voltage difference that maintains the nominal purpose of the circuit. When things go ape and the input voltage difference is much too high or, alternatively, much too low (and that may be a tough nut to crack), the output characteristic will be dependent upon what was connected to ‘+’ and what, to ‘-‘.
    Now, wasn’t that as clear as mud? Remember, I’m constrained to use words, and words alone, as my medium of communication, and, since I have only a fraction of a thousand words, I have only a fraction of a picture!
  • This is an excellent book on linear circuit design, the best I have read to-date. It covers feedback theory, ideal op amps, active filter design & most importantly practical op amp limitations. It also covers voltage regulators, voltage references, ADCs, DACs, op amp noise & more. What I liked most was the combination of mathematical circuit analysis & practical design. Too many books show useful circuits without bothering to explain anything about how they work. It also has plenty of exercises to tax the brain.
