Question 1.
What is voltage gain?
Show hintHide hint
Think about the term 'gain'.
Question 2.
Why is output swing important?
Show hintHide hint
Consider what happens if output goes too high or low.
3Question 3.
What does voltage gain measure?
- 1. Output current to input current
- 2. Output voltage to input voltage
- 3. Total power output to input
Show hintHide hint
Think about what signals are compared.
4Question 4.
True or False: The output swing can exceed the supply voltage.
- True
- False
Show hintHide hint
Consider the limits imposed by the power sources.
Question 5.
Design a common gate amplifier with a specified output swing of ±5V under a 12V supply. Calculate all relevant component values.
Show hintHide hint
Sketch a quick circuit diagram to visualize the relationships.
Question 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.
Show hintHide hint
Utilize the transistor equations to derive parameter needs.
