4Question 4.
True or False: A current mirror can help ensure constant current flow in similar transistors.
- True
- False
Show hintHide hint
Recall its function.
Question 5.
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.
Show hintHide hint
You may need to consider the dual effect of current mirrors and component variability.
Question 6.
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.
Show hintHide hint
Start with gain calculations and then determine necessary components based on input and output characteristics.
