Challenge Problems
Push your limits with advanced challenges
Design a common emitter amplifier with a target voltage gain of 1500 while maintaining collector current of 2 mA. What parameters will you adjust, and how?
💡 Hint: Assess your outputs with respect to collector and base currents' relationship.
If two transistors in a current mirror have a beta mismatch (β of 100 and β of 150), determine the potential impact on the output current if the bias current remains constant.
💡 Hint: Think about how each transistor's β influences the current relations.
