Class Information
Number: 330/156
Name: Amplifiers > Bootstrap coupling
Description: Subject matter wherein the signal input is floating and is applied between the control grid and cathode of a vacuum tube amplifying device, with the cathode having an impedance between it and ground which maintains the cathode voltage above ground, by reason of the anode current flowing through such impedance.
