Challenge Problems
Push your limits with advanced challenges
You have a current amplifier with an unloaded gain of 15 and an input current of 1.5mA. If connected to a 1kΩ load, calculate the output current. Consider the load's effect.
💡 Hint: Calculate how much of the output current flows through the load versus what is available internally.
Design a current amplifier circuit that takes a 1mA input and delivers a 10mA output to a resistive load. Specify the components involved.
💡 Hint: Consider how to ensure the biasing maintains proper current flows.
