Question 1.
What is a current mirror?
Show hintHide hint
Think about how it provides a steady current even with varying loads.
Question 2.
What is the primary function of a common collector amplifier?
Show hintHide hint
Look at how it connects to the transistor's emitter.
3Question 3.
What does a current mirror do?
- Sets a variable current
- Provides a constant reference current
- Amplifies voltage
Show hintHide hint
Consider its primary function in circuits.
4Question 4.
True or False: Current mirrors can help stabilize common mode gain.
- True
- False
Show hintHide hint
Think about how they influence amplifier behavior.
Question 5.
Design a differential amplifier circuit that utilizes current mirrors to enhance gain. Describe the component values and their effects on performance during different operational scenarios.
Show hintHide hint
Review the influence of resistor values in varying common and differential mode scenarios.
Question 6.
Evaluate a typical performance scenario where common mode signals are at play in an amplifier circuit. How do current mirrors specifically help mitigate these effects?
Show hintHide hint
Reflect on the output's sensitivity to common signals and how current mirrors intervene.
