Very technical. Avery good book for the serious experimenter.

People underestimate the transistor, especially the bipolar junction transistor, but as some of you may have found out the hard way, there's more to it. This book explains the math around the equivalent circuits, which is incredibly helpful to the reader, if the reader will take the time to understand the process. Some people criticize this book for favoring the BJT over the JFET, saying that the JFET is becoming more popular, however, the JFET is only popular in chip design and some other specific uses. Don't get me wrong it can be used for amplifying signals, however, it distorts the wave and its high input impedance limits the JFET from use in many other designs. Not only is the BJT simpler it is also better for use in RF design, AF design, and HF design. Take for example, three element oscillator design, the BJT's input and output impedances can be easily changed so that the design is less limited, however, the JFET with its high input impedance limits the design.

This is a good textbook for learning the principle of Transistor circuit step by step clearly.

This is a wonderful book--4 star content--but the tables and diagrams are essential to its usability. To anyone looking for advice, I recommend this book

This book is a great start towards understanding the basis of modern technology. This book is filled with applications of quantum mechanics and how a simple semiconductor revolutionized the world.
