A BASIC TUNNEL DIODE CIRCUIT CONFIGURATION COMPRISINGU: A CHAIN OF SERIES CONNECTED TUNNEL DIODES HAVING DIFFERENT PEAK AND VALLEY CURRENT CHARACTERISTICS, A SOURCE OF BIAS CURRENT COUPLED TO SAID CHAIN, SAID BIAS CURRENT HAVING AN AMPLITUDE INTERMEDIATE THE SMALLEST PEAK CURRENT AMPLITUDE AWND THE GREATEST VALLEY CURRENT AMPLITUDE ASSOCIATED WITH THE TUNNEL DIODES OF SAID CHAIN, SWITCHING MEANS COUPLED TO SAID CHAIN FOR SELECTIVELY ADDING PULSES OF ADDITIONAL CURRENT TO THE BIAS CURRENT FLOWING FROM SAID SOURCE INTO SAID CHAIN, THE SUM OF THE AMPLITUDES OF SAID ADDITIONAL AND BIAS CURRENTS EXCEEDING THE LARGEST PEAK CURRENT AMPLITUDE ASSOCIATED WITH THE TUNNEL DIODES OF SAID CHAIN, AND CONTROL MEANS COUPLED TO SAID SWITCHING MEANS AND TO SAID CHAIN OF TUNNEL DIODES FOR RENDERING SAID SWITCHING MEANS INEFFECTIVE IMMEDIATELY AFTER ONE TUNNEL DIODE CHANGES ITS OPERATING POINT, SAID CONTROL MEANS RENDERING SAID SWITCHING MEANS INEFFECTIVE FOR A PREDETERMINED TIME DURATION SO THAT ONLY ONE TUNNEL DIODE CAN CHANGE ITS OPERATING POINT IN RESPONSE TO EACH PNUT PULSE.
