Challenge Problems
Push your limits with advanced challenges
Design a differential amplifier targeting a 50 dB common mode rejection ratio while providing an output swing of +/- 5V. What parameters must you consider?
💡 Hint: Review the concepts behind resistor selection and biasing network.
If your differential amplifier sees a common mode voltage of 2V and you have a differential input of 0.4V, calculate the expected output if your differential gain is 100.
💡 Hint: Pay attention to the effects of common mode on total output.
