68.1.12. Performance Summary of CE Amplifier with Active Load

Try these first

1. 1.

   What is a common emitter amplifier?

   Hint

   Think about where the emitter is in relation to input and output.

2. 2.

   Define active load.

   Hint

   Consider how this differs from passive elements.

3. 3.

   What is the voltage gain of a CE amplifier with an active load?

   • 218
   • 1923
   • 563

   Hint

   Remember the performance stats discussed.

4. 4.

   True or False: The input resistance of a CE amplifier with passive load will always be greater than that with an active load.

   • True
   • False

   Hint

   Evaluate the characteristics of input resistance.

5. 5.

   Given a common emitter amplifier with active load performing at a gain of 1923. How would altering the input capacitance to 10 nF affect the bandwidth?

   Hint

   Think about how capacitance affects frequency in RC circuits.

6. 6.

   Construct a table comparing voltage gains and bandwidths of both active load and passive load amplifiers under various input conditions.

   Hint

   Utilize experimental results or theoretical calculations in constructing your table.
