Abstract
A pulse amplifier has a first grounded emitter transistor arranged to receive input pulses to change its on-off states in accordance with the presence and absence of the applied pulses and a pair of second and third transistors having their collectors connected in common to a power supply. The second transistor has its base connected to the collector of the first transistor and its emitter connected to the base of the third transistor. The third transistor has its emitter connected to an output terminal from which a high voltage heavy current pulse is obtained so that the pair of transistors change their on-off states alternately with the first transistor. A semiconductor circuit is connected across the emitter and base of the second transistor to instantly put the base potential of the third transistor to a level equal to the base potential of the second transistor when the second transistor changes its state from conducting to nonconducting to thereby assure short decay time at the trailing edge of the output pulse.
