Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
123 words
AN ELECTRICAL CIRCUIT COMPRISING IN COMBINATION: A TUNNEL DIODE HAVING A HIGH CONDUCTANCE IN RESPONSE TO REVERSE BIAS VOLTAGES, A HIGH CONDUCTANCE IN RESPONSE TO RELATIVELY SMALL VALUES OF FORWARD VOLTAGES, LOWER VALUES OF CONDUCTANCE IN RESPONSE TO INTERMEDIATE VALUES OF FORWARD BIAS VOLTAGES, AND A RELATIVELY HIGH CONDUCTANCE IN RESPONSE TO LARGER VALUES OF FORWARD BIAS VOLTAGES, WHEREBY THE AVERAGE CONDUCTANCE IN THE REVERSE BIAS DIRECTION IS GREATER THAN THE AVERAGE CONDUCTANCE IN THE FORWARD BIAS DIRECTION; MEANS FOR APPLYING AN ALTERNATING CURRENT WAVE TO SAID TUNNEL DIODE; AND MEANS PROVIDING A LOAD IMPEDANCE ELEMENT CONNECTED TO SAID TUNNEL DIODE FOR DEVELOPING A DIRECT VOLTAGE COMPONENT THEREACROSS OF A POLARITY WHICH TENDS TO BIAS SAID DIODE IN THE FORWARD BIAS VOLTAGE DIRECTION.
