WebThe input circuit of BJT is forward biased. Hence BJT has low input impedance. FET is a voltage driven device. BJT is a current operated device. In BJT the output current is controlled by the variations in the input current. It produces a current gain. But in a FET, a small voltage at its gate controls the drain current. WebA bipolar junction transistor ( BJT) is a type of transistor that uses both electrons and electron holes as charge carriers. In contrast, a unipolar transistor, such as a field-effect …
