49.2.1. Current Mode Buffer Requirements

Try these first

1. 1.

   What is a current mode buffer?

   Hint

   Think about what type of signal it focuses on.

2. 2.

   Name one configuration used for current mode buffering.

   Hint

   Consider the types of transistors.

3. 3.

   What is the main purpose of a current mode buffer?

   • To amplify voltage signals
   • To amplify current signals
   • To reduce noise

   Hint

   Think about the distinction between current and voltage.

4. 4.

   True or False: High output impedance is beneficial for current mode buffers.

   • True
   • False

   Hint

   Consider the role of impedance in buffering.

5. 5.

   Design a common base amplifier circuit. Describe the components you would use, their connections, and how you would set the biasing conditions.

   Hint

   Consider how you handle the input and output impedances when designing your circuit.

6. 6.

   Explain how you would analyze the frequency response of a common gate amplifier. What factors would you consider?

   Hint

   Consider capacitive effects at different frequency ranges.
