Did you know?
WebBJT is a current controlled device. A normal transistor which we had discussed in the previous chapters come under this category. The functionality, configurations and applications are all the same. Field Effect Transistor. An FET is a three-terminal unipolar semiconductor device. It is a voltage controlled device unlike a bipolar junction ... WebUnipolar Transistor. A unipolar transistor is a FET that uses only one type of charge either electron (n-channel FET) or hole (p-channel FET) for conduction from drain to source. …
WebHence they are called unipolar. But in BJT, both electrons and holes take part in conduction. Hence they are called bipolar. Input circuit (gate -source) is reverse biased. Hence input impedance is high. The 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. WebAug 16, 2024 · As the name indicates BJT is a bipolar device, which means it uses both the electrons and holes as charge carriers to perform its function. ... Bipolar junction …
