Claim 1
Independent Claim
171 words
A HIGH CURRENT GAIN, UNITY VOLTAGE GAIN POWER AMPLIFIER, THE COMBINATION COMPRISING A PHASE-SPLITTER HAVING TWO OUTPUT CIRCUITS, INPUT CIRCUIT MEANS FOR SIMULTANEOUSLY DELIVERING SIGNALS TO SAID PHASE-SPLITTER, FIRST AND SECOND SIGNAL CHANNELS FOR CURRENT AMPLIFYING AND VOLTAGE AND PHASE STABILIZING OF AT LEAST A PORTION OF SAID SIGNALS, WITH EACH CHANNEL HAVING INPUT AND OUTPUT CIRCUITS, SAID OUTPUT CIRCUITS OF SAID PHASE-SPLITTER BEING RESPECTIVELY CONNECTED TO SAID INPUT CIRCUITS OF SAID FIRST AND SECOND CHANNELS, MEANS PROVIDING SUBSTANTIALLY 100% NEGATIVE CURRENT FEEDBACK FROM SAID OUTPUT CIRCUITS OF SAID FIRST AND SECOND CHANNELS TO SAID PHASE SPLITTER, LOAD IMPEDANCE MEANS CONNECTED IN COMMON TO SAID OUTPUT CIRCUITS OF SAID FIRST AND SECOND CHANNELS, SAID FIRST CHANNEL COUPLING A FIRST PORTION OF THE INPUT SIGNAL TO SAID LOAD FOR DEVELOPING A FIRST PORTION OF THE OUTPUT SIGNAL AND SAID SECOND CHANNEL COUPLING A SECOND PORTION OF THE INPUT SIGNAL TO SAID LOAD FOR DEVELOPING A SECOND PORTION OF THE OUTPUT SIGNAL, AND D.C. MEANS FOR PROVIDING OPERATING POTENTIALS FOR SAID POWER AMPLIFIER.
