This is the best book that I have read on noise in microelectronic circuits. The noise equations and treatments are compete for bipolar and MOSFETs. The book is written largely from a discrete transistor level, hence is not as familiar to integrated circuit engineers as say Gray and Meyer, but the treatment is extensive, clear and to the best of my knowledge accurate. This is my favorite book on low noise at the transistor level and I have several.

The book has good coverage of low noise topics and provides examples to reinforce concepts. While I haven't read it thoroughly, it is well organized so I can jump to the topics I'm looking for.

If you have gotten a job to design low-noise amplifiers, or even if you are just a verry serious amateur, you should read this book. I usually work with thousands of volts, so getting a job to design an amplifier for nanovolts was a bit disorienting. Nevertheless, after reading this book, and spending some quality time in the design, I designed an LNA that hit its noise figure. Everything is laid out so logically, and the text is so complete, that the subtitle could be "LNA's for Idiots". I went from total newb to apparent expert in a few weeks. I wish all circuit design books were written this well.

This a very good for basic understanding of noise and noise modelling.
