Claim 1
Independent Claim
147 words
A SWITCHING CIRCUIT COMPRISING: A TRANSISTOR HAVING AN EMITTER, A COLLECTOR AND A BASE; A FIRST IMPEDANCE ELEMENT CONNECTED TO SAID COLLECTOR, MEANS FOR IMPRESSING AN OPERATING VOLTAGES BETWEEN SAID EMITTER AND A TERMINAL OF SAID FIRST IMPEDANCE ELEMENT REMOTE FROM SAID COLLECTOR, A TUNNEL DIODE HAVING FIRST AND SECOND ELECTRODES, A SECOND IMPEDANCE ELEMENT CONNECTED TO SAID FIRST ELECTRODE OF SAID TUNNEL DIODE, MEANS FOR IMPRESSING AN OPERAING VOLTAGE BETWEEN SAID SECOND ELECTRODE OF SAID TUNNEL DIODE AND A TERMINAL OF SAID SECOND IMPEDANCE ELEMENT REMOTE FROM SAID FIRST ELECTRODE OF SAID TUNNEL DIODE, A RESTIVE ELEMENT CONNECTED BETWEEN SAID COLLECTOR AND SAID FIRST ELECTRODE OF SAID TUNNEL DIODE, MEANS COUPLING SAID EMITTER DIRECTLY TO SAID SECOND ELECTRODE OF SAID TUANNEL DIODE, MEANS FOR SUPPLYING A SWITCHING SIGNAL TO SAID BASE AND MEANS FOR DERIVING AN OUTPUT SIGNAL FROM SAID FIRST ELECTRODE OF SAID TUNNEL DIODE.
