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.

A new approach for maximizing op amp behavior in circuit designs- without extensive mathematical analysis This guide from one of the world's leading op amp designers takes you through the causes of op amp performance problems- such as oscillations, errors, bandwidth limitations, noise, and distortion - and shows you how to develop simple models and design equations that lead to optimal results. You'll find detailed solutions for feedback conditions; power supply bypass; phase compensation; reducing radiated interference; and measuring distortion.Combining intuitive and mathematical evaluations, this get-it-done tool packs varied examples that enable you to optimize a range of performance characteristics.
