An electronic supplement to accompany Sedra and Smith's, "Microeletronic Circuits, Fourth Edition". The CD-ROM contains approximately 290 figures from the text, with captions, in Microsoft PowerPoint format. The supplement is intended for use by professors to enhance their lectures through the use of projected images from the text. The figures were originally available in the Instructor's Manual as transparency masters and boxed separately as transparency acetates. Once the current stock of the acetates is depleted, they will not be reprinted. The CD is free to adopters of Sedra/Smith . our continuing effort to maintain the leadership position of this title. The PowerPoint overheads are also available on the OUP-USA College Engineering website for downloading.
