Application of junction field effect transistor (JFET)

There are some important applications of junction field effect transistor (JFET) are given below,

• The junction field effect transistor (JFET) is used as a constant current source.
• The JFET is used as a buffer amplifier.
• The JFET is used as an electronic switch.
• The JFET is used as a phase shift oscillator.
• The JFET is used as high impedance wide band amplifier.
• The JFET is used as a voltage variable resistor (VVR) or voltage development resistor (VDR).
• The JFET is used as a chopper.
