Multipurpose molecular electronic semiconductor device for performing amplifier and oscillator-mixer functions including degenerative feedback means

Claim 1

ELECTRONIC APPARATUS FOR PROVIDING ANY ONE OF A PLURALITY OF CIRCUIT FUNCTIONS INCLUDING THAT OF AN OSCILLATOR-MIXER COMPRISING: A UNITARY BODY OF SEMICONDUCTIVE MATERIAL WITH A PLURALITY OF N AND P TYPE SEMICONDUCTIVE REGIONS THEREIN PROVIDING A FIRST TRANSISTOR FUNCTIONAL PORTION INCLUDING EMITTER, BASE AND COLLECTOR REGIONS, A SECOND TRANSISTOR FUNCTIONAL PORTION INCLUDING EMITTER, BASE AND COLLECTOR REGIONS DISTINCT FROM SAID EMITTER, BASE AND COLLECTOR REGIONS OF SAID FIRST TRANSISTOR FUNCTIONAL PORTION, A CAPACITANCE FUNCTIONAL PORTION, AND A PLURALITY OF RESISTANCE FUNCTIONAL PORTIONS CONDUCTIVELY INTERCONNECTED TO VARIOUS REGIONS OF SAID FIRST AND SECOND TRANSISTOR FUNCTIONAL PORTIONS INCLUDING A FIRST RESISTANCE FUNCTIONAL PORTION CONNECTED TO THE COLLECTOR OF SAID FIRST TRANSISTOR FUNCTIONAL PORTION AND A SECOND RESISTANCE PORTION CONNECTED TO THE COLLECTOR OF SAID SECOND TRANSISTOR FUNCTIONAL PORTION FOR THE PURPOSE OF BIASING SAID TRANSISTOR FUNCTIONAL PORTIONS UPON APPLICATION OF SUITABLE SUPPLY POTENTIAL AT THE EXTREMITY OF SAID RESISTANCE PORTIONS AND A DEGENERATIVE FEEDBACK LOOP COMPRISING AT LEAST ONE OF SAID RESISTANCE FUNCTIONAL PORTIONS INTERCONNECTED BETWEEN THE EMITTER OF SAID SECOND TRANSISTOR FUNCTIONAL PORTION AND THE BASE OF SAID FIRST TRANSISTOR FUNCTIONAL PORTION; A DIRECT CONDUCTIVE INTERCONNECTION BETWEEN THE COLLECTOR OF SAID FIRST TRANSISTOR FUNCTIONAL PORTION AND THE BASE OF SAID SECOND TRANSISTOR FUNCTIONAL PORTION SO THAT SAID DEVICE IS CAPABLE OF SIGNAL AMPLIFICATION WITH A GAIN AT LEAST COMPARABLE TO THAT ACHIEVED IF ONLY SAID FIRST TRANSISTOR FUNCTIONAL PORTION IS UTILIZED WHILE USING A BIAS RESISTANCE CONNECTED TO THE COLLECTOR OF SAID FIRST TRANSISTOR FUNCTIONAL PORTION WHICH IS LESS THAN ABOUT 3000 OHMS; SAID CAPACITANCE FUNCTIONAL PORTION BEING CONNECTED ACROSS THE EMITTER OF SAID SECOND TRANSISTOR FUNCTIONAL PORTION AND A POINT OF COMMON REFERENCE POTENTIAL; FREQUENCY STABILIZING MEANS CONNECTED TO SAID UNITARY BODY BETWEEN TWO CIRCUIT POINTS EACH EFFECTIVELY ASSOCIATED WITH ONE OF SAID REGIONS OF SAID TRANSISTOR FUNCTIONAL PORTIONS TO PROVIDE AN OSCILLATORY SIGNAL AT A FIRST FREQUENCY; MEANS TO SUPPLY A MODULATED CARRIER WAVE AT A SECOND FREQUENCY TO THE BASE OF SAID FIRST TRANSISTOR FUNCTIONAL PORTION MEANS TO DERIVE AN OUTPUT SIGNAL AT THE BEAT FREQUENCY OF SAID FIRST AND SECOND FREQUENCIES FROM THE EMITTER OF SAID SECOND TRANSISTOR FUNCTIONAL PORTION.
