If a BJT differential amplifier is experiencing a significant amount of common-mode noise, what design adjustments could improve its CMRR?
💡 Hint: Think about what design features help to improve signal integrity.
Design a BJT differential amplifier with a target CMRR of at least 60 dB. Given your component values for A_d and A_cm, confirm that your design meets this requirement.
