Challenge Problems
Push your limits with challenges.
Question 1
You have a common emitter amplifier with a collector current of 5 mA and early voltage of 50V. Calculate the required resistance to maintain this current while discussing the effects of any component mismatch.
💡 Hint: You may need to consider the dual effect of current mirrors and component variability.
Question 2
Design a common emitter amplifier circuit that requires a gain of 1000 while using current mirrors for biasing. Specify all components and their values for the desired performance.
💡 Hint: Start with gain calculations and then determine necessary components based on input and output characteristics.
