Challenge Problems
Push your limits with challenges.
Question 1
Design a current amplifier system with specific parameters, including an input current of 10mA, an unloaded current gain of 5, and an output resistance of 1kΞ©. What is the expected output current and how does the load affect it?
π‘ Hint: Consider the circuit as a loading effect and see how the output changes with different load resistances.
Question 2
If you were to connect two current amplifiers in series with the output of the first serving as the input of the second, how would you analyze this combined configuration in terms of current gain and loading effects?
π‘ Hint: Focus on how each amplifier's characteristics can interact through their loading effects.
