WebMar 3, 2007 · Hence, the BJT is a current-controlled device. Specifically, the current through the device (collector to emitter -- assuming an NPN) is a function of the current into the base. And, since you have current flow through the device and some Vce, like the FET's drain to source, you have a resistance, collector to emitter. 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.
