Stabilized transistor amplifier

Claim 1

A SIGNAL AMPLIFIER CIRCUIT PROVIDING A HIGHLY STABLE OUTPUT SIGNAL COMPRISING IN COMBUSTION A FIRST AND A SECOND TRANSISTOR CONNECTED IN CASCADE RELATION, EACH OF SAID TRANSISTORS INCLUDING COLLECTOR, BASE AND EMITTER ELECTRODES, A FIRST AND A SECOND INPUT CIRCUIT COUPLED WITH THE COLLECTOR AND EMITTER ELECTRODES RESPECTIVELY OF THE FIRST TRANSISTOR, AN OUTPUT CIRCUIT COUPLED WITH THE EMITTER ELECTRODE OF THE SECOND TRANSISTOR, A SOURCE OF CIRCUIT ENERGIZING POTENTIAL, A FIRST AND A SECOND BIASING RESISTANCE CONNECTING THE COLLECTOR AND EMITTER ELECTRODES OF SAID FIRST TRANSISTOR RESPECTIVELY WITH GROUND AND THE SOURCE OF ENERGIZING POTENTIAL, SAID RESISTANCES BEING IN PREDETERMINED RATIO TO EACH OTHER, A THIRD AND A FOURTH RESISTANCE FORMING A VOLTAGE DIVIDER NETWORK CONECTED IN SERIES BETWEEN THE EMITTER ELECTRODE OF THE SECOND TRANSISTOR AND THE SOURCE OF ENERGIZING POTENTIAL, SAID THIRD AND FOURTH RESISTANCES BEING IN PREDETERMINED RADIO TO EACH OTHER, MEANS FOR ESTABLISHING DIRECT COUPLINGS BETWEEN THE COLLECTOR ELECTRODE OF THE FIRST TRASNSISTOR AND THE BASE OF THE SECOND TRANSISTOR, BETWEEN THE COLLECTOR ELECTRODE OF THE SECOND TRANSISTOR AND GROUND, AND BETWEEN THE JUNCTION OF THE THIRD AND FOURTH RESISTANCES OF THE SECOND TRANSISTOR AND THE BASE ELECTRODE OF THE FIRST TRANSISTOR RESPECTIVELY.
