Question 1.
Define gain in an electronic circuit.
Show hintHide hint
Think about how the input signal is affected by the circuit.
Question 2.
What is transconductance?
Show hintHide hint
It's a measure of control by input voltage over output current.
3Question 3.
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
Show hintHide hint
Remember how MOSFETs behave in terms of output phase.
4Question 4.
True or False: Gain can be calculated without knowing the output voltage.
- True
- False
Show hintHide hint
Reflect on the definition of gain as a ratio.
Question 5.
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.
Show hintHide hint
Use \\( G = -g_m × R_D \\) to set your values and check with characteristic curves.
Question 6.
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.
Show hintHide hint
Review the definitions of V_GS and output relationships.
