2 cards from this section. Quick, good the night before a test.
What does MOSFET stand for?
Think about the components that make up the acronym.
What is the equation to find the drain current in a MOSFET?
Consider how the gate-source voltage influences the current.
What determines if a MOSFET is in saturation?
Remember the condition for maximum current flow.
True or False: The current in a MOSFET is influenced by the gate voltage.
Think about the relationship between gate voltage and conduction.
Given an N-channel MOSFET with V_dd = 12V, V_gs = 5V, and threshold voltage V_th = 2V, calculate I_D if the transconductance parameter K is 0.5 A/V^2. Also, find the output voltage if R_D = 4Ω.
Watch out for the power ratings in your computations.
Sketch a load line for a common-source N-channel MOSFET circuit with V_dd = 10V and R_D = 5Ω. How would changing R_D affect the operating point?
Identify where the curves intersect for determining the point of operation.
