Claim 1
Independent Claim
195 words
AN AMPLIFYING DEVICE HAVING A VERY STABLE GAIN-TEMPERATURE CHARACTERISTIC WHEN PLOTTED OVER A WIDE AMBIENT TEMPERATURE RANGE, COMPRISING: INPUT TERMINAL MEANS COUPLED TO AN AMPLIFYING TRANSISTOR MEANS, SAID TRANSISTOR MEANS HAVING A CONTROL ELECTRODE COUPLED TO SAID INPUT MEANS AND HAVING FIRST AND SECOND CONDUCTING ELECTRODES, SAID FIRST CONDUCTING ELECTRODE COMPRISING THE OUTPUT POINT OF THE DEVICE AND BEING COUPLED TO A LOAD RESISTOR, THE OPPOSITE END OF SAID LOAD RESISTOR BEING COUPLED TO A POINT OF ONE POTENTIAL, SAID SECOND CONDUCTING ELECTRODE BEING COUPLED TO A DROPPING RESISTOR THE OTHER END OF WHICH IS COUPLED TO A POINT OF THE OTHER POTENTIAL; AND A FEEDBACK NETWORK COMPRISING FIRST, SECOND, AND THIRD RESISTORS, SAID FIRST RESISTOR BEING COUPLED FROM SAID CONTROL ELECTRODE OF SAID TRANSISTOR MEANS TO SAID SECOND CONDUCTING ELECTRODE THEREOF, SAID SECOND AND THIRD RESISTORS BEING COUPLED IN SERIES WITH ONE ANOTHER AND COUPLED IN PARALLE WITH SAID FIRST RESISTOR, THE JUNCTION FORMED BY THE SERIES COUPLING OF SAID FIRST AND SECOND RESISTORS BEING COUPLED TO SAID FIRST CONDUCTING ELECTRODE OF SAID TRANSISTOR MEANS, WHEREIN SAID SECOND AND THIRD RESISTORS ARE OF SUBSTANTIALLY EQUAL VALUE AND ARE OF A VERY HIGH RESISTANCE VALUE
