Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

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.

Challenge 2 Hard

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.
