40.1.3. Recapitulation of Frequency Response

Try these first

1. 1.

   What does frequency response refer to in amplifiers?

   Hint

   Think about the input versus output dynamics.

2. 2.

   Name one capacitance present in a BJT.

   Hint

   Recall the connections in a BJT structure.

3. 3.

   What aspect of amplifiers does frequency response measure?

   • A) Input current only
   • B) Output response to various frequencies
   • C) Power usage only

   Hint

   Think about what distinguishes different frequency signals.

4. 4.

   True or False: Miller's theorem is only applicable for resistive elements.

   • True
   • False

   Hint

   Consider the types of elements we've discussed.

5. 5.

   Given a common source amplifier with a small-signal voltage gain of 5 and significant gate-drain capacitance, calculate the equivalent input capacitance using Miller’s theorem.

   Hint

   Start with understanding the relationships from Miller's theorem.

6. 6.

   For a BJT common emitter amplifier experiencing high frequencies, analyze how neglecting the base-collector capacitance can affect the circuit's functionality.

   Hint

   Think about how frequency response shifts can impact function.
