Abstract
PURPOSE: To obtain an output signal having no distortion, by connecting 2 resistances in series between output terminals of the first and second amplifying circuits, and negative-feeding back the voltage in the connecting point between said resistances, to the second amplifier.
CONSTITUTION: An electric power amplifying circuit 2 and 3 contain a driver, respectively, and to an operational amplifier 4, an input of the circuit 2 and output voltage are inputted. Also, the impedance 7 and 8 are connected between output terminals of the circuit 2 and 3, respectively, and an output current i2 and i3 are synthesized and outputted. Also, between the output terminals, a resistance 5 and 6 are connected in series, and the connecting point of the resistance 5 and 6 is connected to an inverted input terminal of the operational amplifier 4. In this way, voltage of this connecting point is negative-fed back to the circuit 3, and equalizes 2 input terminals of the amplifier 4. As a result, an output signal having no distortion can be obtained.
