That is not correct, a BJT is basically a current amplifying device.. If a voltage comes out of a BJT based amplifier that voltage is either the BJT's collector current which is turned into a voltage by a resistor connected to the BJT's collector or the BJT is used as a voltage buffer (common … fixscratchtmWebDec 27, 2010 · BJT is called Bipolar instead of a Unipolar like MOSFET or JFET. As you can see, both holes and electrons are active carriers. Electrons and Holes are opposite poles (i.e. having opposite polarities), thus calling any transistor with such distinction a Bipolar Junction Transistor. Jan 24, 2005. fix scratch porcelain sink
