Question 1.
What does a common drain stage in an amplifier do?
Show hintHide hint
Think about the function of a follower.
Question 2.
Define voltage gain.
Show hintHide hint
Ratio gives us the gain.
3Question 3.
What is the role of a common drain stage in amplifiers?
- Increases voltage gain
- Buffers voltage
- Reduces noise
Show hintHide hint
Think about the functionality of the common drain.
4Question 4.
True or False: Cascading a common drain stage will decrease the overall gain.
- True
- False
Show hintHide hint
Consider the purpose of such a design.
Question 5.
Design a circuit that cascades two amplifier stages, ensuring an overall gain of 10 while limiting the upper cutoff frequency to 1 MHz. Provide R and C values.
Show hintHide hint
Remember that cascading can involve trade-offs.
Question 6.
If the first stage has an upper cutoff frequency of 500 kHz, and the second stage has a cutoff of 1 MHz, what is the overall cutoff frequency when both stages are cascading?
Show hintHide hint
Which stage creates the greater limitation?
