A differential amplifier using BJTs has a transconductance of 30 mS and a load resistance of 1.5kΩ. What is its differential gain?
💡 Hint: Use the transconductance and load resistance to find the gain.
If a differential amplifier's common mode gain is measured at 2 V/V, while its differential gain is 50 V/V, calculate the Common Mode Rejection Ratio (CMRR).
💡 Hint: Recall the formula for CMRR to calculate the answer.
