EVALUATION OF HIGH-SPEED TWO-TUBE CONFIGURATIONS. PART I. GREATER GAIN- BANDWIDTH IN TRIGGER CIRCUITS. PART II. TRANSIENT ANALYSIS OF THE WHITE CATHODE FOLLOWER (thesis)
S>The relation between switching speed of a trigger circuit and the gain band width (GBW) of an amplifier is discussed. A series connection of two tubes, referred to as a dynamic plate-load amplifier (DPL), is also presented and analyzed. A d-c analysis shows that the DPL investigated has 18% of the output impedance and 2.75 times the d-c gain of a conventional amplifier. A transient analysis shows that the DPL may have 3 times the advantage in GBW over a conventional amplifier. The GBW is recommended for utilization in fast trigger circuits. A regeneration analysis of the DPL trigger circuit is included. The White cathode follower, a two-tube series device that provides output impedances of the order of 5 ohins, which transmits pulses of either polarity with minimal distortion is described. A d-c and transient analysis of the White cathcde follower is made and a typical circuit analyzed. The effect on the transient respcnse of varying the circuit parameter is discussed and throughout the paper the White cathode follower is compared with 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. (auth)
