Challenge Problems
Push your limits with challenges.
Question 1
Design a three-stage amplifier with specified gains of 20, 10, and 5. Include calculations for overall input and output resistance considering loading effects. What design strategies do you adopt?
💡 Hint: Consider both individual gain and the relationships of input/output resistances.
Question 2
Given a two-stage amplifier where Stage 1 has a gain of -100 and output resistance of 1kΩ, and Stage 2 has a gain of 2 and an input resistance of 50kΩ, calculate the effective voltage gain and discuss potential loading effects.
💡 Hint: Use the voltage divider concept for effective gain calculations.
