Challenge Problems
Push your limits with challenges.
Question 1
A current mirror circuit requires a collector current of 5 mA. If the β of all transistors is 150 and base current is considered non-negligible, calculate the required bias resistance.
💡 Hint: Remember to account for base current in your calculations.
Question 2
An amplifier circuit with a nominal input voltage of 0.5V, output voltage gain of 1000, determines the corresponding output voltage.
💡 Hint: Notice how the gain impacts the output voltage significantly.
