35.3.1. Frequency Response of Common Source and Common Emitter Amplifier

Try these first

1. 1.

   What does frequency response indicate?

   Hint

   Think about amplifier behavior over varying signals.

2. 2.

   What is a common emitter amplifier?

   Hint

   Recall its properties and use it in applications.

3. 3.

   What is the frequency response of an amplifier?

   • The output signal varies with temperature.
   • The output varies with input frequency.
   • Both input and output must be constant.

   Hint

   Consider what changes in input frequencies mean for output.

4. 4.

   The cutoff frequency is where the gain drops to _____ dB.

   Hint

   Remember the significance of decibels in this context.

5. 5.

   Design a common emitter amplifier for an application that requires a specific frequency range. Outline the necessary parameters and components.

   Hint

   Use the equations discussed for calculating cutoff frequency.

6. 6.

   Given an RC circuit transfer function, analyze its frequency response and verify its behavior at specified frequencies.

   Hint

   Focus on identifying poles and gain at key frequency markers for the circuit.
