Solid-state electronics has been a familiar technology for almost half a century@ yet some circuit ideas@ like the transresistance method of finding amplifier gain or identifying resonances above an amplifier's bandwidth that cause spurious oscillations@ are so simple and intuitively appealing that it is a wonder they are not better understood in the industry. I was blessed to have encountered them in my earlier days at Tektronix but have not found them in engineering textbooks. My motivation in writing this book@ which began in the late 1980s and saw its first publication in the form of a single volume published by Academic Press in 1990@ has been to reduce the concepts of analog electronics as I know them to their simplest@ most obvious form@ which can be easily remembered and applied@ even quantitatively@ with minimal effort.
