A JFET can be either a current-controlled device or a voltage-controlled device.

More Questions from Field Effect Transistors (FET)

• The charge carriers in a junction field effect transistor (JFET) will flow from source to drain in a p-channel and from drain to source in an n-channel.
• In a voltage-divider JFET circuit, ID is a maximum when VGS = 0 V.
• An enhancement-type MOSFET or E-MOSFET can be turned on when the channel is depleted.
• A MOSFET has an isolated gate.
• The gate-biased JFET characteristic curve includes IDS.
• A JFET has 3 terminals: gate, drain, and source.
• A JFET is very similar to a BJT.
• The amount of gate voltage needed to turn the JFET completely off is called VGS(OFF).
• Transconductance is also called mutual conductance.
• A common-drain configured JFET is also called a source-follower.
