Question 1.
What is V_out in a common source configuration with V_in = 5V if R_D = 1kΩ?
Show hintHide hint
Remember to consider the operating region of the MOSFET.
Question 2.
Define transconductance (g_m).
Show hintHide hint
It relates to how effectively the device controls output based on input.
3Question 3.
What does the load resistor (R_D) affect in a MOSFET circuit?
- Output Voltage
- Gate Voltage
- Threshold Voltage
Show hintHide hint
Consider how current flowing through R_D would affect V_out.
4Question 4.
True or False: The gain of a MOSFET circuit is determined by the equation -g_m * R_D.
- True
- False
Show hintHide hint
Recall the definition of gain and the parameters involved.
Question 5.
Design a circuit using a NMOS with specific parameters (V_th = 2V, R_D = 100kΩ) and a V_dd of 12V. Calculate V_out for both saturation and triode regions.
Show hintHide hint
Graphically illustrate the load lines to validate your calculations.
Question 6.
A specific NMOS has g_m = 5 mA/V and R_D = 10kΩ. Calculate the gain and predict the output if V_in varies from V_th + 1V to V_dd.
Show hintHide hint
Check for any potential changes in operating regions when V_in approaches V_dd.
