4Question 4.
True or False: A cascode transistor decreases the output resistance.
- True
- False
Show hintHide hint
Think about the configuration and its purpose.
Question 5.
Design a current mirror that can handle a reference current of 2 mA using BJTs, ensuring that each transistor's size is appropriately calculated for heavy load conditions.
Show hintHide hint
Refer back to how different sizes affect current output in mirrors.
Question 6.
Evaluate how decreasing the supply voltage to 5V from 12V affects the output current and overall circuit performance of your designed current mirror.
Show hintHide hint
Consider how resistive losses may affect the current when supply voltage changes.
