Rightfully considered a classic in the field, and its third edition was highly anticipated for many years.

This book's niche is in building the intuitive understanding that is often lacking after the typically highly mathematical treatment seen in 200-level circuit theory courses. It's a great transition from "ok, I can manipulate the equations for a circuit with one or two transistors" to being able to design complete, practical electronic devices. The book is also heavily used as a cookbook and reference by practicing electronics engineers as it contains a lot of expert wisdom particularly in the area of high-precision analog circuits (the authors' background is in physics lab instrumentation design).
