Challenge Problems
Push your limits with challenges.
Question 1
Design a simple current amplifier model that can react to an input current of 3 mA with an expected unloaded gain of 5. What would be the unloaded output current? Now, what if a load of 10 ohms is connected?
💡 Hint: Calculate the output using the gain and consider the effect of adding the load.
Question 2
Explain how a change in temperature could affect the operation of a current amplifier configured using BJTs. What practical measures can be taken to mitigate these effects?
💡 Hint: Think about how external conditions influence electronic components.
