This market-leading Microelectronics Circuits textbook continues its standard of excellence and innovation built on the solid pedagogical foundation that Adel S. Sedra and Kenneth C. Smith have shared with more than one million students to date. All material is thoroughly updated to reflect changes in technology. These technological changes have shaped the book's organization and topical coverage, making it the most up-to-date resource available for tomorrow's engineers learning how to analyze and design electronic circuits. The 'must-cover' topics are placed first in each chapter, the more specialized material appears last. Chapters 1to 5 are organized to form a coherent single-semester introductory course. Similarly, Chapters 6 to 9 and 13 present a body of material for a second one-semester course. Finally, Chapters 11 and 12 can be used to supplement a third course on analog circuits and Chapters 10, 14 and 15 can be used as about half of a senior-level course on digital IC design.
