Such topics are covered in specialized monographs numbering many hun- dreds, but the voluminous nature of this literature limits access for students. This book is the outcome of attempts to develop a broad course on devices and integrated electronics for university students at about senior-year level. The edu- cational prerequisites are an introductory course...
