54.2.6. Current Gain Analysis

Try these first

1. 1.

   What is the common gate amplifier?

   Hint

   Think about where the input and output connections are made.

2. 2.

   Define voltage gain.

   Hint

   How do we measure performance in amplifiers?

3. 3.

   What defines the input impedance of an amplifier?

   • Output Voltage
   • The impedance at the input
   • Current Gain

   Hint

   Think about the characteristics of input and output configurations.

4. 4.

   True or False: The output swing of an amplifier can exceed the supply voltage.

   • True
   • False

   Hint

   Recall the voltage relations we examined in class.

5. 5.

   Design a common gate amplifier configuration that achieves a voltage gain of 10 with given specifications. Outline step-by-step calculations you'll perform.

   Hint

   Focus on working equations for gain calculations.

6. 6.

   Consider a common base amplifier and analyze how higher input impedance affects voltage gain. Justify your analysis.

   Hint

   Think about how input signal travels through the amplifier.
