A TRIGGER CIRCUIT COMPRISING A TUNNEL DIODE HAVING AN ANODE AND A CATHODE, A D.C. VOLTAGE SOURCE HAVING A NEGATIVE AND A POSITIVE TERMINAL, SAID POSITIVE TERMINAL BEING CONNECTED TO A GROUND REFERENCE POINT, MEANS FOR BIASING SAID TUNNEL DIODE FOR BISTABLE OPERATION, SAID BIASING MEANS INCLUDING A FIRST RESISTOR CONNECTED BETWEEN THE ANODE OF SAID TUNNEL DIODE AND SAID REFERENCE POINT AND A SECOND RESISTOR CONNECTED BETWEEN THE CATHODE OF SAID TUNNEL DIODE AND THE NEGATIVE TERMINAL OF SAID D.C. VOLTAGE SOURCE, A FIRST DIODE HAVING ITS ANODE CONNECTED TO THE CATHODE OF SAID TUNNEL DIODE AND ITS CATHODE CONNECTED TO A JUNCTION POINT, A LIKE-POLED SERIES DIODE COMBINATION HAVING A THRESHOLD OF CONDUCTION DIFFERENT FROM THAT OF SAID FIRST DIODE, SAID DIODE COMBINATION HAVING ITS FREE ANODE TERMINAL CONNECTED TO THE ANODE OD SAID TUNNEL DIODE AND ITS FREE CATHODE TERMINAL CONECTED SAID TUNNEL TION POINT, AN INPUT TERMINAL, A SIGNAL DIFFERENTIATING NETWORK CONNECT BETWEEN SAID INPUT TERMINAL AND SIAD JUNCTION POINT, A PNP TYPE TRANSISTOR HAVING ITS BASE ELEMENT CONNECTED TO THE ANODE OF SAID TUNNEL DIODE, MEANS FOR RESISTIVELY COUPLING THE COLLECTOR AND EMITTER ELEMENT OF SAID TRANSISTOR TO THE NEGATIVE TERMINAL OF SAID D.C. SOURCE AND SAID REFERENCE POINT RESPECTIVELY AND MEANS FOR COUPLING A PAIR OF OUTPUT SIGNALS FROM THE COLLECTOR AND EMITTER ELEMENTS OF SAID TRANSISTOR RESPECTIVELY.
