Try these first

1. 1.

   What is the main purpose of a current mirror?

   Hint

   Think about why current stability is essential in amplifiers.

2. 2.

   What is single-ended signaling?

   Hint

   Consider how many lines of wire are involved.

3. 3.

   What does a current mirror do in a circuit?

   • Generates high voltage
   • Maintains constant current
   • Amplifies power

   Hint

   Focus on what it stabilizes.

4. 4.

   True or False: Differential signaling makes amplifiers more susceptible to noise.

   • True
   • False

   Hint

   Think about its noise handling capabilities.

5. 5.

   Design a basic current mirror circuit and explain its operation. Discuss how it would behave under varying input voltages.

   Hint

   Consider how feedback might play into this design.

6. 6.

   Analyze the impact of a failed current mirror on the output signal of a differential amplifier. What can be done to ensure reliability?

   Hint

   Think about methods to stabilize circuits against failure.
