WebThe key difference between BJT and JFET is that BJT is a device in which output current is controlled by the base current. On the contrary, JFET is a device whose output current is controlled by the input voltage applied to it. BJT possess low to medium input impedance whereas when we talk about JFET, it possesses high input impedance. WebBJT is a current controlled device. It means it uses the input current at its base terminal to control the output current or collector current. By connecting the base-collector junction in reverse and base-emitter junction in forward bias allows the flow of current between emitter and collector.
