The Cathode-Coupled Amplifier

This paper gives the reader a picture of the operation of the cathode-coupled amplifier and a study of methods of application in several new directions. Among these are the following: high-frequency amplifiers, multivibrators, audio oscillators, radiofrequency oscillators, resonant-resistance determination, mixers, and other applications. This list is by no means all-inclusive, but does show some of the capabilities of this unique circuit.
