2.3. Current Mirror and Biasing Circuits

Try these first

1. 1.

   What is the purpose of a current mirror in a circuit?

   Hint

   Think about how mirrors reflect something.

2. 2.

   What does differential signaling reduce?

   Hint

   Remember, it's about two signals working together.

3. 3.

   What is a current mirror used for?

   • To amplify signals
   • To maintain constant current
   • To reduce noise

   Hint

   Consider what mirrors do in real life.

4. 4.

   True or False: Differential signaling uses one signal to transmit data.

   • True
   • False

   Hint

   Think about the term 'differential' itself.

5. 5.

   Design a differential amplifier circuit that incorporates a current mirror for biasing. Explain your choices.

   Hint

   Consider the implications of transistor matching on performance.

6. 6.

   Evaluate the performance issues in an amplifier circuit without feedback. What potential problems could arise?

   Hint

   Reflect on how feedback stabilizes and controls amplifier gain.
