Challenge Problems
Push your limits with challenges.
Question 1
Design a trans-conductance amplifier with specified parameters including a gain factor of 50 and analyze the output resistance with feedback. Explain the adjustments needed for non-ideal conditions.
💡 Hint: Consider the relationships among voltage, current, and feedback in your design.
Question 2
If a trans-conductance amplifier operates with a finite input resistance of 10kΩ and an output resistance of 4kΩ, calculate the expected output resistance under negative feedback with a β of 0.1.
💡 Hint: Use the expression derived in class to connect these parameters effectively.
