3 cards from this section. Quick, good the night before a test.
What happens to current if W is increased?
Think about the effect of area on charge flow.
What is the threshold voltage (Vth)?
Consider it the baseline voltage for operation.
Which component primarily determines the resistance in a MOSFET?
Consider how distance affects flow in a circuit.
True or False: Pinch-off occurs when VDS is too low.
Think about the conditions that create pinch-off.
Given a MOSFET with dimensions W=8μm, L=2μm, VGS=5V, Vth=1V, and VDS=4V. Determine the current flowing through the device under the assumptions of ideal behavior.
Set up your K based on (W/L) and input your voltage values correctly.
If you increase the drain voltage VDS while keeping all other parameters constant in a circuit where the current is in saturation, what would be the physical implication in the MOSFET's operation?
Remember, saturation limits the effect of higher VDS on current.
