Question 1
You are designing a differential amplifier with a target differential gain of 100. If you have a resistor of 2kΞ©, what must the transconductance (g_m) be?
π‘ Hint: Think about rearranging the gain formula to isolate g_m.
Question 2
A BJT differential amplifier outputs an inverted signal of -5V when inputs of +2V and -2V are applied. Determine the common mode gain if both input signals were adjusted to +2V.
π‘ Hint: Evaluate the characteristics of identical input signals.
