This text develops a comprehensive understanding of the basic techniques of modern electronic circuit design, analog and digital, discrete and integrated. It provides balanced coverage of analog and digital circuits. A broad spectrum of topics is included, and material can be easily be selected to satisfy either a two- or three-semester sequence in electronics. Sufficient depth of material is also provided so the text can be used for senior electives in either digital or analog circuit design. Computer usage is integrated throughout the text in the form of circuit simulation using SPICE, problem solving using MATLAB, spreadsheets and computer programs. The text includes comprehensive problem sets at the end of each chapter that are keyed to the sections in the book and graded in level of difficulty. Numerous design problems are also included.
