37.1. Frequency Response of CE and CS Amplifiers (Part C)

Try these first

1. 1.

   What is frequency response?

   Hint

   Consider how gain changes with frequency.

2. 2.

   What does the symbol 'g' represent in an amplifier circuit?

   Hint

   Think about output current over input voltage.

3. 3.

   What type of amplifier configuration is a CE amplifier?

   • inverting
   • non-inverting
   • differential

   Hint

   Think about the behavior of the output in relation to the input.

4. 4.

   True or False: The lower cutoff frequency depends on the output capacitance.

   • True
   • False

   Hint

   Review what conditions affect cutoff frequencies.

5. 5.

   A CE amplifier has a transconductance of 40 mS and an output resistance of 2 kΩ. Calculate the voltage gain.

   Hint

   Use the formula for gain involving transconductance.

6. 6.

   Describe how you would approach determining the frequency response for a CE amplifier including both upper and lower cutoff frequencies.

   Hint

   Consider the roles of each component's values in the circuit.
