Challenge Problems
Push your limits with advanced challenges
Given a differential amplifier with a low common mode gain and its transconductance specified, design a similar circuit with a current mirror. Identify potential challenges.
💡 Hint: Refer back to the current mirroring effects discussed.
Assume a circuit yields incorrect biasing due to high common mode gain. Redesign it using calculations for ideal current mirror values.
💡 Hint: Use known relationships to recalculate.
