23.6.2. Transconductance Amplifiers

Try these first

1. 1.

   What defines a transconductance amplifier?

   Hint

   Think about the input-output relationship.

2. 2.

   What is the primary component often used in transconductance amplifiers?

   Hint

   Which transistor type do we regularly discuss in class?

3. 3.

   What is the role of the coupling capacitor in a transconductance amplifier?

   • Blocks DC
   • Amplifies output
   • Provides bias

   Hint

   What happens to DC signals at the input?

4. 4.

   True or False: Transconductance amplifiers only work with voltage inputs.

   • True
   • False

   Hint

   What type of signal is primarily used?

5. 5.

   Given a BJT with specified parameters, design a transconductance amplifier circuit. Explain the value selections for resistors and how they influence the circuit performance.

   Hint

   Look for the relationships between biasing settings and the stability of the amplifier.

6. 6.

   Evaluate the performance of a transconductance amplifier in a specific audio application. Consider factors such as distortion and feedback mechanisms.

   Hint

   Explore how different materials can change the quality of the signals.
