Question 1
What is the voltage gain formula for a CG amplifier?
- A_V = g_m (R_D + R_L)
- A_V = g_m (R_D || R_L)
- A_V = R_L / R_D
💡 Hint: Think about how resistances combine in parallel.
Question 2
True or False: A CG amplifier typically has a high input impedance.
- True
- False
💡 Hint: Recall the properties of CG amplifiers.
