Challenge Problems
Push your limits with advanced challenges
You have a differential amplifier with Ad = 75 and Acm = 0.15. Calculate the CMRR in both linear and decibel forms.
💡 Hint: Dividing Ad by Acm gives you CMRR, remember to apply the log function for dB!
Design a BJT differential amplifier targeting an Ad of 100 and a CMRR of 90 dB. Specify your resistor values and explain your choice.
💡 Hint: Focus on balancing gain performance versus noise rejection for optimal design!
