Question 1.
What is the typical voltage gain formula for a common source amplifier?
Show hintHide hint
Think about how output voltage relates to input voltage.
Question 2.
Define the term upper cut-off frequency in your own words.
Show hintHide hint
Consider the impact of frequency on amplifier behavior.
3Question 3.
What is the voltage gain of a typical common source amplifier?
- 1
- 6
- 10
Show hintHide hint
Think about the multiplication of parameters to find the gain.
4Question 4.
The upper cut-off frequency indicates the point where the output signal...
- is maximized
- is reduced to 70.7% of the maximum
Show hintHide hint
Consider what happens to the signal at that frequency.
Question 5.
A compound amplifier system consists of a CS amplifier with a 6 dB gain followed by a CD stage. If the CD stage has an input resistance of 10 kΩ, how would you calculate the output resistance and overall bandwidth?
Show hintHide hint
Reflect on how each stage affects output and perform series-parallel resistance calculations.
Question 6.
Given a common source amplifier with a load capacitance of 100 pF and an output resistance of 3 kΩ, derive the upper cut-off frequency. Determine how the frequency shifts when a CD stage is added.
Show hintHide hint
Understanding the impact of C and R changes in series and parallel configurations is key.
