This complete text on op-amp use and design discusses topics essential to the practicing engineer that are not covered in comparable texts, including error budget analysis, noise analysis, active filters, and op-amps with multiple poles. The text can be used as a supplement in many electronics courses. It has a practical emphasis and coverage of SPICE computer modeling, satisfying the latest ABET recommendations for more design emphasis in EE courses. It uses commercially available op-amps rather than theoretical models in examples and problems to familiarize students with actual devices. It also provides unusually extensive coverage of active filters, one of the most significant current uses of op-amps--and includes data sheets for the most widely used op-amps.Kennedy, E. J. is the author of 'Operational Amplifier Circuits Theory and Applications' with ISBN 9780030019487 and ISBN 0030019486.
