Question 1
What is the formula for calculating gain in a circuit with a MOSFET?
- G = g_m × R_D
- G = -g_m × R_D
- G = R_D/g_m
💡 Hint: Remember how MOSFETs behave in terms of output phase.
Question 2
True or False: Gain can be calculated without knowing the output voltage.
- True
- False
💡 Hint: Reflect on the definition of gain as a ratio.

Challenge Problems
Push your limits with challenges.
Question 1
Design a MOSFET amplifier circuit with given specifications: gain of 10, supply voltage of 12V, and ensure the device operates within the saturation region. Provide calculations and justifications.
💡 Hint: Use \\( G = -g_m × R_D \\) to set your values and check with characteristic curves.
Question 2
You are given a circuit with a MOSFET and a load resistor. If the output voltage is 6V, and input current is 2mA, compute transconductance and ensure proper calculation of the gain.
💡 Hint: Review the definitions of V_GS and output relationships.
