Transient Analysis of the White Cathode Follower

Abstract

The White cathode follower is a two‐tube series device that provides output impedances of the order of 5 ohms and transmits pulses of either polarity with minimal distortion. A dc and transient analysis of the White cathode follower is made, and a typical circuit is analyzed. The effect on the transient response of varying the circuit parameters is discussed. Throughout the paper the White cathode follower is compared to the well‐known conventional cathode follower. The White cathode follower may have an advantage in gain‐bandwidth over the conventional cathode follower by a factor of five.
