Excerpt from Introduction to Noise in Solid State Devices This is a didactic monograph intended to be readable by physicists and electronic engineers with only general background, and should be of particular value to beginners of applied work in the field of noise. Others who wish to gain an understanding of this important phenomenon also will profit. The attempt has been made here to simplify a complex subject, and the text is mainly qualitative. An aim is to impart a feel for the subject, and while the treatment generally is not rigorous, it is not misleading. Although noise reduction as an ultimate goal is a main concern, the premise is that a basic under standing of noise processes forms a necessary base for the applications engineer or scientist as well as for the device designer. This monograph is divided into two parts. The first, Theory, deals in detail with each of the four principal noises found in solid state devices The emphasis here is on phenomenological aspects of noise, its origins, and its manifestations. The second part, Applications, is a systematic treatment of noise in selected solid state devices. Analyses progress from a single noise source in a circuit element to four noise sources in a device; concomitantly equivalent circuits are developed to facilitate the solution of various complex noise problems. The devices considered here were chosen as much for illustrative value as for commercial importance or currentness. They reveal the evolutionary nature of electron devices and the transfer of concepts from the earlier to the later devices, thus providing a simplifying coherence. Because of the way this work is structured, it should be read successively. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
