3 cards from this section. Quick, good the night before a test.
Define I_DS in a MOSFET.
Think about how current is categorized based on terminals.
What is the relationship between W, L, and I_DS?
Consider what happens to current if channel width or length changes.
What determines I_DS in a MOSFET?
Look at all parameters influencing current, not just one.
The threshold voltage V_th is essential for current flow.
Consider current flow requirements in MOSFETs.
A MOSFET has W = 5 µm, L = 1 µm, and characteristics yielding K = 100 µA/V^2. If V_GS = 3V and V_th = 1V, what is I_DS if V_DS = 2V?
Use the current expression and substitute values carefully.
Discuss how adjusting W and L can optimize current flow for a specific application in a circuit using MOSFET.
Think about what each parameter does in terms of current and resistance.
