Challenge Problems
Push your limits with challenges.
Question 1
Design a small signal model for a current mirror circuit with given parameters (transistor sizes, bias currents) and derive the output characteristics.
💡 Hint: Break down the circuit into manageable parts and analyze each component carefully.
Question 2
Critically analyze a circuit where a current mirror fails to accurately mirror current due to non-ideal elements and suggest improvements.
💡 Hint: Reflect on real-world limitations and consider matching transistor characteristics.
