WebThe bipolar junction transistor (BJT) is a current-controlled device whereas the field effect transistor (FET) is a voltage-controlled device as shown in the figure at right. In each case the current of the output circuit is controlled by a parameter of the input circuit— in one case a current level (IB) and in the other an applied voltage (VGS). WebApr 16, 2024 · On the other hand, a transistor that is current controlled, has current as the controlling parameter. This means that the flow of current at the output terminals is controlled by a current at the input terminal. Output current is a function of an input current.
