What does JFET mean?

The simplest field-effect transistor is called Junction Field Effect Transistor(JFET). It is used in the front ends of sensitive circuits. JFET works as a low noise amplifier in the sensitive circuits as gate oxide does not consist in JFET.

There are two types of Field Effect Transistors (FET)

• Junction Field Effect Transistor (JFET)
• Insulated-gate Field Effect Transistors (IGFET)

Further, there are two types of JFET

• n- channels
• p- channels

Advantages of Junction Field Effect Transistor

• A high degree of isolation is allowed between the input-output circuit because JFET has a very high input impedance.
• The smaller size of the JFET makes it highly efficient and increases its life.
• There is no risk of the thermal runway being involved in the JFET because the resistance temperature coefficient of JFET is negative.
• The power gain of JFET is very high.

Disadvantages of JFET

• JFET is costly and has a low voltage gain.
• JFET has to be handled with care as it has higher chances of damage when mishandled.
• Compared to the conventional transistors, the gain-bandwidth product of JFET is minimal.

Applications of JFET

• Junction Field Effect Transistor is used as a buffer amplifier.
• JFET works well as a voltage variable and as a chopper.
• JFET is a high impedance wideband amplifier and high input impedance amplifier.
• One can use JFET as a voltage development resistor.
• JFET works effectively as a constant current source and phase shift oscillator.
• Junction Field Effect Transistor is applicable in RF and cascade amplifiers.

Why do we need JFET biasing?

By using the JFET biasing technique, we can change the fixed voltage. JFET drain current is kept controlled by a biasing process, and a single resistor accompanies a source pin.
