Question 1.
What does a current mirror do in a differential amplifier?
Show hintHide hint
Think about the 'copying' function.
Question 2.
What is the DC current if there's a 12V supply and a 11.4 kΩ resistor?
Show hintHide hint
Use Ohm's Law: V = IR.
3Question 3.

- True
- False
Show hintHide hint
Consider the effectiveness of noise filtering.
Question 5.
Design a differential amplifier circuit using MOSFETs with current mirrors. Describe your design choices and expected outputs.
Show hintHide hint
Consider matching parameters and controlling bias currents.
Question 6.
Analyze a differential amplifier where the DC current through one transistor is 2 mA. Given a load resistance of 100 kΩ, calculate the expected voltage at the output.
