Pulse forming and shaping circuit employing a charge-storage diode

Claim 1

A PULSE GENERATING CIRCUIT COMPRSING, A SIGNAL GENERATOR FOR PRODUCING SIGNALS HAVING AT LEAST TWO DIFFERENT LEVELS, CHARGE STORAGE MEANS CONNECTED IN SHUNT WITH SAID SIGNAL GENERATOR, SAID CHARGE STORAGE MEANS BEING CAPABLE OF FORWARD CURRENT CONDUCTION AND CHARGE STORAGE IN RESPONSE TO ONE LEVEL SIGNAL PRODUCED BY SAID SIGNAL GENERATOR AND LIMITED REVERSE CURRENT CONDUCTION AND CHARGE RECOMBINATION WITH ULTIMATE NONCONDUCTION IN RESPONSE TO A DIFFERENT LEVEL SIGNAL PRODUCED BY SAID SIGNAL GENERATOR WHEREBY A FAST RISE-TIME SIGNAL IS PRODUCED THEREACROSS, ENERGY STORING MEANS CONNECTED IN SHUNT WITH SAID CHARGE STORAGE MEANS SUCH THAT ENERGY IS STORED THEREIN DURING THE LEADING EDGE OF SAID FAST RISE-TIME SIGNAL AND RELEASED THEREAFTER IN ORDER TO SUPPLEMENT THE TRAILING EDGE OF SAID SIGNAL, DIFFERENTIATING NETWORK MEANS CONNECTED TO SAID ENERGY STORING MEANS TO PROVIDE A PREDETERMINED NEGATIVE SLOPE AT THE TRAILING EDGE OF THE SIGNAL PRODUCED ACROSS SAID CHARGE STORING MEANS, AND TRANSISTOR MEANS CONNECTED TO SAID DIFFERENTIATING NETWORK MEANS, SAID TRANSISTOR MEANS CHARACTERIZED BY FAST TRANSIENT CONDUCTION WITH LITTLE AMPLIFICATION AND A VARYING AMPLIFICATION FACTOR WHICH IS RELATED TO THE NEGATIVE SLOPE OF THE TRAILING EDGE OF THE SIGNAL PRODUCED BY SAID DIFFERENTIATING NETWORK SUCH THAT A SUBSTANTIALLY FLAT-TOP SIGNAL IS PRODUCED BY SAID TRANSISTOR MEANS.
