Such circuits make ideal isolation circuits orfbutfers, and are extensively used to couple low impedance loads to high impedance voltage sources, especially where the phase or polarity inversion characteristic of ordinary amplifiers is to be avoided. Cathode follower circuits are characterized as having high input impedance, low output impedance and a voltage gain which approaches unity. In the electronic arts generally, and particularly in the communication, TV, computer, automatic control and instrumentation arts, cathode followers are extensively used. so-called totem-pole amplifiers with tubes only
