58.1.2. Introduction to Multi Stage Amplifiers

Try these first

1. 1.

   What configuration provides high voltage gain?

   Hint

   Think about the basic function of each configuration.

2. 2.

   What is the role of a Common Collector (CC) stage?

   Hint

   Recall how the CC stage relates to input and output impedance.

3. 3.

   What is the primary function of a CE amplifier?

   • a) Buffering
   • b) High Voltage Gain
   • c) Oscillation

   Hint

   Consider the purpose behind using each amplifier type.

4. 4.

   True or False: CC stages can enhance the bandwidth of an amplifier.

   • True
   • False

   Hint

   Reflect on the effects of coupling different stages together.

5. 5.

   Design a multi-stage amplifier with specific gain requirements. Calculate the necessary component values for the CE and CC stages to achieve both gain and bandwidth.

   Hint

   Work through each formula step-by-step to find the values.

6. 6.

   Analyze the effect of changing the load resistance on the performance of a multi-stage amplifier in a given circuit schematic.

   Hint

   Look at how impedance and circuit loading relate to amplifier gain.
