This is one of the more polished books I've come across as a student. The concepts are explained very well for each section with many various examples to support them. This is a good introductory book for people who want to get into circuit design. It talks about diodes, transistors, and amplifiers in general. There are also many blue boxes that relate what is learned to either history or the industry. The only things to look out for in the book are the deriviations of the equations. There are a lot of equations in the book and some of those equations are hard to derive just by looking at the previous equations. This book also builds up on and refers to previous chapters, so it might not make sense if you start at a later chapter. Although the price for this book is very high, I would still recommend this book. It is on a higher quality level than many other books out there.
