Question 1.
What is the purpose of buffering in amplifier circuits?
Show hintHide hint
Think about how stages interact.
Question 2.
What happens to gain when amplifiers are cascaded?
Show hintHide hint
Consider the effects of resistance.
3Question 3.
What is the primary issue when cascading CE or CS amplifiers?
- Increased gain
- Reduced gain due to loading effects
- Increased bandwidth
Show hintHide hint
Consider what happens to the output when two stages are closely connected.
4Question 4.
True or False? Buffers are only required for Common Emitter amplifiers.
- True
- False
Show hintHide hint
Think about the function of buffers in general.
Question 5.
You cascade two amplifiers, one with a gain of 20 and the other with a gain of 5. However, due to loading effect, you find an attenuation factor of 0.75. Calculate the overall gain.
Show hintHide hint
Use the overall gain formula discussed in class.
Question 6.
Design a buffer circuit for two amplifiers, considering you need a high input resistance and low output capacitance. Describe your design.
Show hintHide hint
Think about components that have appropriate performance characteristics.
