Question 1.
What is the formula for voltage gain (A_v)?
Show hintHide hint
Consider the relationship between output and input resistances.
Question 2.
Define transconductance (g_m).
Show hintHide hint
Think about the current-voltage relationship in amplifiers.
3Question 3.
What is the voltage gain formula for a Common Source Amplifier?
- AV = -RGm
- AV = RGm
- AV = -RDg
- AV = RDg
Show hintHide hint
Focus on the roles of resistance and transconductance.
4Question 4.
True or False: The input resistance of a Common Source Amplifier is zero.
- True
- False
Show hintHide hint
Consider how resistors are connected in the circuit.
Question 5.
Consider a Common Source Amplifier with an input signal of 1V and R_D as 2 Ω. If g_m is 4 mA/V, calculate the output voltage.
Show hintHide hint
Remember the voltage gain formula.
Question 6.
If a high-frequency oscillation leads to a decrease in gain due to Miller capacitance, what can be done to mitigate this effect?
Show hintHide hint
Think of ways to manage capacitance.
