The Graphical Design of Cathode-Output Amplifiers

This report describes a convenient graphical method for analyzing and designing cathode-followers. It considers the details of operation only so far as they are essential to this description. The familiar equivalent circuit analysis is presented first for convenience. This is followed by a description of the graphical method, a discussion of its application for triode and pentode cathode followers, and instructions for sketching the graphs quickly and conveniently.
