Ah, my favorite subject. A BJT, FET, and thermionic vacuum tubes are all transconductance devices (voltage controls current). True, you can incorporate them into voltage amplifying, current amplifying, etc circuits, but by themselves, they are all transconductance devices. The base current of BJT does not control the collector in the BJT's active mode. It is only a useful indicator the the collector current. It is also waste current that has to be taken into consideration. The bias voltages applied to a device are not considered to be a DC amplification. Much of the BJT literature avers that a BJT is a current amplifier, but that is not true. A BJT by itself is essentially a current source controlled by a voltage. I await questions and comments.
