Sedra & Smith vs Razavi vs Neamen — Which Microelectronics Textbook?
Quick Answer: Sedra & Smith is the UK standard — rigorous, design-oriented, prescribed at most UK EEE departments. Razavi is the intuitive alternative — its ‘analysis by inspection’ framework develops engineering instinct faster. Neamen is the most accessible but least common at UK universities. Most students need one of the first two.
If your reading list specifies Sedra & Smith, buy it. If it specifies Razavi, buy that. If neither is specified, Sedra & Smith is the safer UK default — more widely prescribed, more comprehensive, more design-oriented. Add Razavi if you want the intuitive ‘inspection’ complement.

Sedra & Smith — Microelectronic Circuits
Sedra/Smith (8th ed, OUP, 2020) is both a teaching text and a professional reference — the book students buy as undergraduates and keep on their desk throughout their careers. Its defining strength is its design orientation: rather than stopping at analysis (how does this circuit work?), Sedra/Smith consistently pushes to design (how do I choose the components so it works the way I need it to?). The 8th edition is significantly slimmed from the 7th, removing peripheral material and tightening the core microelectronics curriculum.
Key strengths: Comprehensive coverage; strong on device physics foundations; excellent on frequency response and feedback (two topics many books underserve); design-oriented worked examples; free online Premium Resources.
Where it’s demanding: The device physics sections (semiconductor junctions, MOSFET I-V characteristics) are rigorous and can slow students down early. Razavi’s more device-agnostic approach is faster to get into circuit-level analysis.
Razavi — Fundamentals of Microelectronics
Razavi’s ‘analysis by inspection’ framework is the book’s defining contribution. Rather than always writing KVL/KCL equations, students learn to determine circuit gain and impedances directly from the circuit topology — a skill that experienced circuit designers use constantly. This approach is efficient, intuitive, and closer to how electronics is actually practised.
Key strengths: Faster to circuit-level analysis; outstanding intuition-building examples; excellent MOSFET-focused content for modern CMOS design; self-test questions with answers let students check their understanding immediately.
Where it’s lighter: Less comprehensive than Sedra/Smith on device physics; feedback analysis is less deeply developed; slightly weaker on the BJT-dominant circuits that still appear in many UK curricula.

Our Verdict
⚖ The Verdict
Buy Sedra & Smith (ISBN 9780190853464) as your primary text for most UK EEE courses. It is the standard, the most comprehensive, and the best for design-oriented assessment.
Buy Razavi (ISBN 9781119695141) if your department prescribes it, or add it as a complement to Sedra for the ‘analysis by inspection’ perspective.
Skip Neamen unless it is prescribed — Sedra or Razavi is the right choice for UK students.
💰 Save Money
Used copies of Sedra/Smith 7th ed and Razavi 2nd ed are available on AbeBooks from £20–40. Core analogue electronics content (small-signal models, frequency response, feedback) is essentially unchanged between editions. Check whether your module assigns problems from a specific edition.
Is Sedra & Smith or Razavi better for electronic engineering?
Sedra & Smith is better for rigorous, design-oriented study and is the most widely prescribed text at UK EEE departments. Razavi is better for developing circuit intuition quickly through its ‘analysis by inspection’ framework. Many students find both useful: Razavi for intuition, Sedra/Smith for exam-level rigour.
Which edition of Sedra & Smith should I buy?
The 8th edition (ISBN 9780190853464, OUP, 2020) is current. Used 7th editions are available cheaply. The 8th edition is significantly slimmed from the 7th, focusing on the core curriculum. Check whether your module’s problem sets reference specific editions before buying used.
Is Razavi Fundamentals of Microelectronics suitable for UK undergraduate courses?
Yes — Razavi’s 3rd edition (ISBN 9781119695141) is widely used at UK universities as either a primary text (Bath, Leeds, Sheffield) or a supplement to Sedra/Smith. Its analysis-by-inspection framework is particularly valued at UK institutions that focus on circuit intuition alongside mathematical rigour.
Do I need both Sedra & Smith and Razavi?
Not necessarily — one is sufficient for most EEE modules. Many students who own both report using Razavi to build initial intuition and Sedra/Smith for exam preparation and design coursework. If you can only buy one, buy whatever your reading list prescribes, or Sedra/Smith as the UK default.
