54.2.5. Voltage Gain Calculation

Try these first

1. 1.

   What is voltage gain?

   Hint

   Think about the term 'gain'.

2. 2.

   Why is output swing important?

   Hint

   Consider what happens if output goes too high or low.

3. 3.

   What does voltage gain measure?

   • 1. Output current to input current
   • 2. Output voltage to input voltage
   • 3. Total power output to input

   Hint

   Think about what signals are compared.

4. 4.

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

   • True
   • False

   Hint

   Consider the limits imposed by the power sources.

5. 5.

   Design a common gate amplifier with a specified output swing of ±5V under a 12V supply. Calculate all relevant component values.

   Hint

   Sketch a quick circuit diagram to visualize the relationships.

6. 6.

   Given an input impedance requirement of 300Ω for a common base amplifier, discuss how you would configure the transistors and find possible resistor values.

   Hint

   Utilize the transistor equations to derive parameter needs.
