Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Design an input stage of an op-amp with the following specifications: Ad = 200, Target CMRR_dB = 80, I_tail = 400 microamperes. How do you calculate the required RC and RE_effective?

💡 Hint: Keep track of whether your calculations require single-ended or differential output considerations.

Challenge 2 Hard

Given a circuit with a high-frequency pole frequency, strategize how to implement compensation to maintain stability. Discuss potential techniques.

💡 Hint: Think about how each alternative impacts phase and gain.
