Abstract
Signal source output resistance and negative feedback resistance all contribute to restrain transistor non-linearity and improve amplifier linearity. Amplifier sine output voltage and transistor emitting junction non-sine voltage coexist. Transistor emitting junction non-sine voltage is a byproduct and doesn't affect amplifier function. It was proved by experiment and in theory that the input signal magnitude in the basic common-emitter amplifier is not limited with small signal extent condition Ubem≤10mV, and output range is not limited with Ubem≤10mV. It was proved that small signal amplifier conception does not accord with the facts and might be not suitable.
