44.2.3. Conclusions on Buffer Operation

Try these first

1. 1.

   Define output resistance.

   Hint

   Think about how it relates to the load connected to an amplifier.

2. 2.

   What is input capacitance?

   Hint

   What happens when you connect a capacitor to a battery?

3. 3.

   What is the impact of low output resistance in amplifiers?

   • Increased signal distortion
   • Reduced signal distortion
   • No impact at all

   Hint

   Think about load characteristics.

4. 4.

   True or False: High input impedance is desirable in amplifiers.

   • True
   • False

   Hint

   Think about how an amplifier interacts with the source.

5. 5.

   Design a circuit using a common drain amplifier to achieve a specific voltage gain of 1.5, considering component values.

   Hint

   Start by selecting an appropriate transistor and consider how the resistor values impact gain.

6. 6.

   Analyze how loading a common collector amplifier with a load resistance affects its performance and provide calculations for a specific load.

   Hint

   What happens to output voltage when you apply Ohm's law to the circuit with a load?
