Correct Answer
Gate



Question 2
What produces current flow in a FET?
Correct Answer
Positive bias attached to drain



Question 3
What forms the barrier in a FET?
Correct Answer
Negative bias attached to gate



Question 4
Is the gate to source forward or reverse biased in a FET?
Correct Answer
Reverse biased



Question 5

Question 6
What is JFET cutoff?
Correct Answer
a large negative gate voltage that increases junction barrier so much that current
flow stops (vgg > vdd)



Question 7
What is JFET saturation?
Correct Answer
A negative gate voltage so small that decreases the junction barrier to a point
where it no longer decreases, constant current flow



Question 8
What causes constant current flow in JFET?
Correct Answer
JFET saturation



Question 9
What causes current flow to stop in JFET?
Correct Answer
JFET cutoff



Question 10
What controls large source to drain currents?
Correct Answer
Small reverse bias voltages
