Optimizing Op Amp Performance Review

Average Reviews:

(More customer reviews)This book is an excellent treatment of this subject that is intuitive and not overly theoretical. It draws together a lot of material available in magazines and on vendor websites, but not available in book format. The author starts with the traditional op amp symbol, and derives Black's classic feedback model for various configurations (inverting, non-inverting, etc) of the op amp. A generalized expression for the closed loop gain is eventually obtained where the numerator is the ideal closed loop gain, and the denominator contains the frequency response that can be analyzed with the aid of the Bode plot. Practical design issues are logically addressed using this simple formalism including bandwidth, phase compensation for input and output capacitances, power supply by-pass requirements, distortion, etc. Care is taken to indicate what conclusions apply to all op amp configurations, and which address specific design issues. As a writer, the author is very pointed in his approach and thorough with his analyses; and will not win any awards for fiction suited for a general audience. However, I highly recommend the book to anyone trying to learn how to use op amps in a systematic way.

Analog and Digital Filter Design, Second Edition (EDN Series for Design Engineers) Review

Average Reviews:

(More customer reviews)It is a nice, easy to read description of analog and digital filtering. Nevertheless, I think that the digital filtering chapters are not enough to explore the potentialities of digital filters and the book would benefit from more practical project examples.
On the overall, it is good for a first approach to filtering, but the reader might need something else for a deeper view of the topic.

Electric Motors and their Controls: An Introduction Review

Average Reviews:

(More customer reviews)This is a great book.
This book is precise and informative, comprehensive and yet very easy to read. Without laboring over theory, it gets right to the heart of all types of electric motors and controls, covering all facets from classic to futuristic. The author fully understands the field and does not obscure the hard-to-understand areas; rather, the author illustrates the operation of each type of motor in a form that YOU WILL LEARN from, even to the point of following current flow through the motor windings so that you will see the causes of motor operation, and the genius of modern motor design.
Even if you think you know all there is to know about how electric motors work, this book will fill the gaps in your understanding.

High-Power Audio Amplifier Construction Manual Review

Average Reviews:

(More customer reviews)... Randy Slone regurgitates no one; he states in his own words, clearly and in accessible language for the non-specialist, established principles of solid state amplifier design, and places these in the context of his suggested projects. One chapter is devoted to twelve "ready-to-construct" cookbook designs, and full-size PC board artwork for several of these are provided in an appendix. In short, if you want to build and/or design your own audio power amplifiers, this is an excellent resource.
Randy Slone begins with the basics of acoustics relating to audio power amplifiers and methodically walks the reader through a variety of designs, ranging from old to new, and simple to complex. As one would expect, much of this information is founded upon well established research. There is also a significant portion devoted to new techniques and principles of amplifier physics which help to de-mystify amplifier operation and provide pathways to improved performance. Unlike many similar textbooks that focus on only one topology or design philosophy, Randy Slone examines the broad range of amplifier configurations and power capabilities, including mirror-image input stages, fully-complementary VA stages, paralleled output stages, and lateral MOSFET designs.
Randy Slone may be somewhat opinionated, but his opinions appear to be logical reflections of measurable facts; and as any good scientist knows, that what cannot be measured does not exist for the world of science and engineering. He makes short shrift of tube cult; these are devices that produce measurable distortion and can never compete with the power capacity of modern solid state systems. The writing style and technical descriptions are easy to follow although a background in electronic fundamentals is helpful. No more than high school algebra is needed. Occasional humor increases the reading pleasure. Randy Slone has the somewhat eccentric habit of discussing current flow as if it traveled from negative to positive pole, while the convention is to describe it moving the other way. Once the reader becomes accustomed to this way of thinking - not too silly for electrons do indeed travel from negative to positive - it becomes easier to read. It is a complete resource for designing and constructing your own high-quality audio power amplifier systems.
I am currently building myself six of Randy Slone's OPTIMOS kits after reading the book. The fact that Randy Slone also sells the kits from his web site is a highly positive feature. Imagine trying to source all those components and make the PCBs yourself. Furthermore, Randy Slone is always available to help with specific questions and suggestion on a one to one basis. He really does answer his e-mail.
Highly recommended.

Analog Design Essentials (The Springer International Series in Engineering and Computer Science) Review

Average Reviews:

(More customer reviews)There is a haphazard and unfinished feel to this book. This book has some good design information, but it can jump from the elementary to the advanced in the same chapter. It does not follow the conventional textbook style, but simulates a Powerpoint presentation, with two slides per page. I think there is an over-reliance on the slides. For example, about one hundred of the slides contain nothing but portions of the overall table of contents. Even books for further reading are listed in slides.
The main problem, however, is that EVERY slide is fuzzy, as though it had been printed with an old inkjet printer. The resolution of EVERY illustration is so low (near fax quality), that I cannot read some of the circuit diagram labels (see, for example, picture no. 2142 on page 658).
I also have a problem with the accompanying CD. It contains 24 pdf files, with a total size of 15 gigabytes (note, not 15 megabytes but 15 gigabytes) in an ordinary CD! Each file is larger than 600 megabytes, and there are 24 such files! Of course, this is not physically possible with an ordinary CD (only 700 megabytes total), nor even with a DVD. It means that the CD's file directory must have been manipulated so that it has a non-standard format which somehow tricks the computer into believing that the CD has 15 gigabytes. As I have discovered, you can open the pdf files with Acrobat Reader, but you cannot copy them to your hard disk (the file copy will fail). Therefore you must leave the CD in the drive all the time. In any case, these pdf files offer nothing extra, because they contain precisely the same low-resolution pictures that you find in the physical book, nothing more and nothing less, and also at the same low resolution (fax quality).

Photodiode Amplifiers: OP AMP Solutions Review

Average Reviews:

(More customer reviews)This book lives up to its title by giving a thorough review of photodiodes driving op-amps. It does not consider specialized, discrete photodiode amplifiers. By limiting the coverage to op-amps, the bandwidths are necessarily those of op-amps, a few tens of megahertz at the time most of the book was written, perhaps 100 MHz or so today. Truly wide bandwidth solutions (GHz) are left to the imagination of the reader.

Light photons impinging upon a semiconductor material in the vicinity of a P-N junction release conduction carriers to produce current flow through the photodiode effect. Photodiode amplifiers convert thiscurrent to a voltage in a relationship that remains linear as long as the amplifier eliminates signal voltage swing from the photodiode. For this purpose, the simple current-to-voltage converter or transimpedance amplifier presents a virtual ground to the diode. However, when connected to a photodiode, this simple op amp circuit displays surprising multidimensional constraints that defy conventional op amp intuition.

Analog Circuits (World Class Designs) Review

Average Reviews:

(More customer reviews)World class? Here's a review of some of the chapters: Review of Feedback systems....Basic Operation Amplifier Topologies....review of passive components and a case study in PC board layout, 4 chapters if you can believe it--on filter design, a chapter on noise....all of these represent basics, rudimentary material an EE grad should have mastered...and can hardly be considered world class. Some of the remaining chapters: How to Design Analog circuits without a computer....My approach to feedback design...Jim Williams "zoo circuit", while having their merits....can all be found in the "EDN series for
design engineers". And to publish Pease's notes on Vbe.....Pulease, Pease.... "What's all this vbe stuff" can be found online for free.
In summary, this text will help augment an undergraduate EE's education. It might be useful for non-hardware or digital designer types who have to stray out of their comfort zones, into the analog domain. But there is little in this text that actually world class. Williams Zoo circuit is the the only world class design. Everything else is either rudimentary, or a rip off of other previous published material.
I downgraded the text to 3 stars because the text is somewhat deceptive as to what it purports to be. It should be more appropriately titled: "Analog Circuits: Basics To Be Mastered". The authors are competent, and well known in the field, so it wasn't downgraded any further.

Electric Motors and Control Techniques Review

Average Reviews:

(More customer reviews)Overall I found this to be an excellent book. I enjoyed every page, and in particular tracing out circuit operations of the various schematics. I thought the diversity of circuits was great.
Nowhere in the title did I see "Basics of" or Fundementals of". This is not a book for the novice. The reader must have a good understanding of AC and DC motors, and solid state theory, circiuts, and devices.
I found the concatenation of induction motors, and the Kramer speed control system very interesting. I have many old industrial control books, but none shows these systems.
There are several errors, and examples of such are: Page 44, Para 3 is completely wrong. The proper way to reverse direction of compound motors is to reverse A1 and A2. Page 57, para 2 relates to this proper method. Fig. 5-9 Q102 shows a JFET- should be a UJT. Fig. 5-13 Q1 same thing. Fig. 5-10 has negative 250 VDC lines to emitters of Q532-Q536 and Q552-Q556 missing. Eliminate lead from motor to bottom of C541. Fig. 6-11 motor will never reverse with this scheme. Turning dial in opposite direction FWD biasis Q2 turning on Q1 which energizes RY2. RY1 drops out turning system off. Motor never runs CCW.
I have a comprehensive technical library, and one of my books is by this author entitled "Design and Operation of Regulated Power Supplies". It's an old book, and it's full of solid state circuits. I am indebted to authors like Mr Gottlieb, for it's their writings that enabled me to learn solid state electronics.
