WebApr 16, 2024 · Difference #1 between a BJT and JFET: Current vs Voltage controlled . Earlier you would have seen that the BJT is a current controlled device, whereas the JFET is voltage controlled. This is the first major difference between a BJT and JFET. But what does it mean if a transistor is current or voltage controlled? 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. This current is directly proportional to the base ...
