Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Design a differential amplifier with specific values for R_C and R_E. Calculate the expected A_d and A_cm, and evaluate the CMRR. Discuss any assumptions applied in your design.

💡 Hint: Make sure to account for real-world variances in component values.

Challenge 2 Hard

Analyze how increasing temperature affects transistor parameters in a differential amplifier. Describe how this might alter the differential gain and common-mode gain.

💡 Hint: Apply knowledge of thermoelectric properties of materials to your explanation.
