33.5.7. Trans Conductance Amplifier

Try these first

1. 1.

   What does trans conductance measure?

   Hint

   Think about how output current depends on input voltage.

2. 2.

   Define output resistance.

   Hint

   Look for the definition related to load interaction.

3. 3.

   What parameter does trans conductance represent?

   • Input voltage to output voltage ratio
   • Output current to input voltage ratio
   • Resistance seen at the input

   Hint

   Relate it to the definition of controlling current.

4. 4.

   Does a higher input resistance decrease loading effects?

   • True
   • False

   Hint

   Think about how high resistance interacts with signals.

5. 5.

   Design a trans conductance amplifier with specific trans conductance and expected input/output conditions. What considerations must you take regarding bandwidth?

   Hint

   Think about how capacitances affect the flow and clarity of signals.

6. 6.

   If a trans conductance amplifier has a trans conductance of 4 mA/V and a load of 1 kΩ, what would be the expected output current? Discuss the implications of changing load resistance on the output.

   Hint

   Apply Ohm's Law and consider how loads interact with amplifier output.
