Transistor avalanche mode pulse generator

Claim 1

A PULSE GENERATOR, COMPRISING: FIRST AND SECOND SIMILAR CONDUCTIVITY TYPE TRANSISTORS, EACH HAVING AVALANCHE MULTIPLICATION CHARACTERISTIC AND HAVING AN EMITTER ELECTRODE, A COLLECTOR ELECTRODE AND A BASE ELECTRODE; AN OUTPUT TERMINALS; A FIRST CAPACITOR ASSOCIATED WITH AND FOR COUPLING THE COLLECTOR ELECTRODE OF SAID FIRST TRANSISTOR TO GROUND POTENTIAL; A FIRST RESISTOR COUPLING THE EMITTER ELECTRODE OF SAID FIRST TRANSISTOR TO SAID OUTPUT TERMINAL; A SERIALLY ARRANGED SECOND CAPACITOR AND SECOND RESISTOR COUPLING THE COLLECTOR ELECTRODE OF SAID SECOND TRANSISTOR TO SAID OUTPUT TERMINALS; MEANS FOR COUPLING SAID SECOND TRANSISTOR EMITTER ELECTRODE TO GROUND POTENTIAL; THIRD AND FOURTH RESISTORS FOR COUPLING THE COLLECTOR ELECTRODES OF SAID FIRST AND SECOND TRANSISTORS, RESPECTIVELY, TO FIRST AND SECOND VOLTAGE SOURCES, RESPECTIVELY; MEANS COUPLED TO THE BASE ELECTRODES OF SAID FIRST AND SECOND TRANSISTORS AND ADAPTED TO RECEIVE A TRIGGER PULSE FOR TRIGGERING ONE OF SAID TRANSISTORS INTO AN UNSTABLE AVALANCHE CONDITION DURING WHICH AVALANCHE BREAKDOWN OCCURS IN THE EMITTER-BASE-ELECTOR JUNCTIONS OF SAID ONE TRANSISTOR TO PERMIT ITS ASSOCIATED CAPACITOR TO DISCHARGE CURRENT THERETHROUGH AND ACROSS ITS ASSOCIATED RESISTOR IN A FIRST DIRECTION AND AFTER A PREDETERMINED TIME INTERVAL FOR TRIGGERING THE OTHER OF SAID TRANSISTORS INTO AN UNSTABLE AVALANCHE CONDITION DURING WHICH AVALANCHE BREAKDOWN OCCURS IN THE EMITTER-BASE-COLLECTOR JUNCTIONS OF SAID OTHER TRANSISTOR TO PERMIT ITS ASSOCIATED CAPACITOR TO DISCHARGE CURRENT THERETHROUGH AND ACROSS ITS ASSOCIATED RESISTOR IN A SECOND AND OPPOSITE DIRECTION; SAID OPPOSING DIRECTIONED CURRENTS SUBSTANTIALLY CANCELING EACH OTHER AT SAID OUTPUT TERMINAL EXCEPT DURING SAID PREDETERMINED TIME INTERVAL.
