The international edition is typically a softcover version with slightly different problem numbers or SI unit emphasis. It is not a different textbook. The legal ways above will often specify “International Edition” if you search by the correct ISBN (check your syllabus).
It’s definitely a popular textbook for anyone diving into electrical engineering, but I can’t provide a direct link or a PDF of the 8th International Edition of Microelectronic Circuits (by Sedra and Smith). Sharing copyrighted textbooks would violate copyright laws.
However, I can help you find a copy through the right channels or assist you with the material if you're currently studying it! Where to find it legitimately:
University Library: Most engineering schools have several copies in the library or offer digital access through their institutional login (like VitalSource or O'Reilly).
Oxford University Press: This is the official publisher. They often have companion websites with student resources, errata, and sometimes discounted digital rentals.
Used Bookstores: Sites like AbeBooks or ThriftBooks are great for finding the International Edition (which is often much cheaper than the North American version) at a fraction of the price.
Rental Services: Amazon or Chegg usually offer semester-long rentals for a much lower cost than buying. If you’re studying right now:
Since that book is famous for being quite dense (especially the chapters on MOSFET biasing and Operational Amplifiers), I can help you break down specific problems or concepts. If you'd like, let me know:

Do you need help with PSpice or NI Multisim simulations related to the book's examples?
I'm happy to walk through a tough circuit diagram or explain the math behind a specific derivation with you!
The Microelectronic Circuits 8th International Edition by Sedra and Smith is a foundational textbook for electrical and computer engineering students. The 8th edition, released in 2020, has been updated for greater modularity and flexibility, featuring approximately 1,400 problems—half of which are new or revised. Legitimate Access and Resources
While unofficial PDF versions are sometimes found on document-sharing platforms, users are encouraged to access the text through authorized channels to ensure accuracy and compliance with copyright laws.
Official Publisher Site: The Oxford Learning Link provides official student and instructor resources, including summary tables, SPICE simulation guides, and data sheets for commercial devices.
Enhanced E-Book: An enhanced electronic version is available from retailers like RedShelf and University Book Store, which includes embedded problem-solving videos and interactive features.
Library Lending: Many university and local libraries offer eBook lending services for this edition. Key Features of the 8th Edition
Streamlined Content: The authors removed nearly 200 pages of non-essential material to focus on core fundamentals and modern IC design. The international edition is typically a softcover version
Updated Pedagogy: Introduced "essential problems"—a curated subset (35–40%) of end-of-chapter problems to guide focused study.
New Coauthors: Tony Chan Carusone and Vincent Gaudet joined the author team to provide fresh research and teaching perspectives.
Technological Alignment: Numerical values in examples and exercises were revised to reflect the parameters of modern submicron technology nodes. Related Educational Materials Microelectronic Circuits 8e Student Resources

ISBN‑13: 978‑0198821156
| Audience | Fit | |----------|-----| | Undergraduate EE majors (Junior/Senior) | Excellent primary textbook; covers all required topics for a typical “Microelectronics” or “Analog Circuits” course. | | Graduate students (first‑year) | Useful as a reference for device modeling and as a refresher on classic analog design. | | Practicing Engineers | Good for quick lookup of MOSFET small‑signal parameters or design‑centering guidelines, especially for low‑power CMOS. | | Self‑learners | The book is clear, but you’ll need access to a SPICE tool and possibly supplemental video lectures (available via the OUP site with a purchase). |
| Part | Chapter(s) | Main Topics | What’s New in 8th Ed. | |------|------------|-------------|-----------------------| | I | 1‑3 | Fundamentals, Semiconductor physics, Diodes | Updated diode leakage models for modern CMOS processes | | II | 4‑7 | MOSFET fundamentals, BJT fundamentals, Small‑signal models | Revised MOSFET SPICE models (BSIM4/6) and new BJT Gummel‑Poon parameters | | III | 8‑12 | Amplifiers (single‑stage, multistage), Op‑amp basics | Added low‑power op‑amp design for sub‑1 V supplies | | IV | 13‑16 | Frequency response, Feedback, Stability | Expanded discussion of phase‑margin measurement with modern oscilloscopes | | V | 17‑19 | Oscillators, Multivibrators, Signal‑Processing building blocks | New PLL (phase‑locked loop) design example using 65 nm CMOS | | VI | 20‑23 | Data converters (ADC/DAC), Sample‑and‑hold circuits | Inclusion of SAR‑ADC architecture and calibration techniques | | VII | 24‑27 | Power management, Switch‑mode regulators, Low‑power design | Chapter on GaN/SiC power devices and their gate‑drive considerations | | VIII | 28‑30 | Digital CMOS design, Timing, Noise, Layout considerations | Updated CMOS scaling trends and design‑for‑manufacturability (DFM) tips | | Appendices | A‑E | Math refresher, SPICE tutorial, Device tables, Solution manual references | Online supplemental video lectures (access code provided with textbook) |
Renting is cheaper if you only need the book for one semester.
In many courses, the 7th or even 6th edition covers 95% of the same core topics (diodes, BJTs, FETs, op-amps, feedback). Instructors often allow older editions. Older editions are:
