Question 1
What is the formula for Differential Gain (A_d)?
- A_d = g_m * R_C
- A_d = -g_m * R_C/2
- A_d = -R_C/R_E
💡 Hint: Pay attention to the terms involving the gain.
Question 2
True or False: A high common-mode gain is desired in amplifiers.
- True
- False
💡 Hint: Think about the implications of noise.
