How can we tell if a differential amplifier working well? From its CMRR, Ad and Acm
True or False Increasing RE improves the CMRR for single-ended output by increasing the differential-mode gain anddecreasing the common-mode gain. Increasing RE reduces the transistor DC currents and increases the DC output voltages. The double-ended output of the differential amplifier is always zero if vs1=vs2 for any value of RE.
