4 cards from this section. Quick, good the night before a test.
What does JFET stand for?
Think about the full form of JFET.
Is a JFET a voltage-controlled or current-controlled device?
Remember how it regulates current flow.
What type of device is a JFET?
Think about what governs the flow in JFET.
The cut-off voltage of JFET refers to what?
Recall what happens when the voltage reaches this threshold.
If a JFET has a maximum drain current of 10 mA at VGS=0V and the cut-off voltage is -3V, what will be the drain current at VGS=-1.5V?
Substitute your known values carefully into Shockley’s equation.
Describe the significance of controlling current by gate voltage in practical applications. How does this feature benefit electronic designs?
Consider the impact on efficiency in circuits.
