36. The drain current of the N-channel JFET increases with
- Definition: JFET is the shortened form for J unction F ield E ffect T ransistor. It is a 3 terminal semiconductor device in which current conduction takes place only due to the flow of majority charge carriers. Thus, it is a unipolar transistor. The 3 terminals of the JFET are source, drain and gate.
- JFET is a voltage-controlled device as it is controlled by use of a reverse bias voltage to the gate terminal. The channel gets drained and the electric current becomes switched off. A Junction Field Effect Transistor is usually said to be on when there is no voltage between the gate and the source pin.
- This post is about structure, parameters and properties of JFET transistor. JFET transistor is a three-terminal device, where one of the terminal can control current between two others. JFET transistor terminals are drain (D), source (S) and gate (G). Here current between D and S can be controlled by gate-source voltage.
