For a differential amplifier configured with transistors having a total collector current of 2mA and resistances of 10kΩ at the collectors, if Vid = 500mV, calculate Ad.
💡 Hint: Keep in mind that Ad will be negative due to the phase shift.
If a differential amplifier has an Acm of 1V and Ad of 25, what is the CMRR in dB?
💡 Hint: Remember to convert to decibels following the formula provided.
