TRANSISTOR AMPLIFIER FOR BROAD-BAND INFORMATION SIGNALS

摘要

A broad-band transistor amplifier comprising a negative feedback circuit for maximum negative feedback as well as a circuit with which in the manner of a negative feedback exclusively the distortion products occurring in the output signal of the amplifier are subjected to a feedback for the purpose of additionally reducing these distortion products. To this end the transistor amplifier includes a cascade arrangement of two impedances whose common connection point is connected to the input of a phase inverter stage which injects the distortion products in phase opposition into the output circuit of the amplifier.
