Question 1.
What is the primary limitation on voltage gain in a common emitter amplifier?
Show hintHide hint
Think about how passive components interact with power supply limitations.
Question 2.
How does replacing a passive load with an active load theoretically improve gain?
Show hintHide hint
Consider the changes in current-voltage characteristics.
3Question 3.
What is the primary factor limiting voltage gain in common emitter amplifiers?
- Output load resistance
- Input signal voltage
- Collector resistor voltage drop
- Transistor type
Show hintHide hint
Consider how the supply and output components interact.
4Question 4.

- True
- False
Show hintHide hint
Reflect on the different transistor designs they utilize.
Question 5.
Design a common emitter amplifier with a targeted voltage gain of 100. What component values would you choose considering practical limitations?
Show hintHide hint
Ensure that the voltage at the output does not saturate for the intended input signal range.
Question 6.
Examine a common source amplifier that has a maximum allowed Vdd of 10V and aims for a gain of 5. Calculate the ideals for resistor values when connected to a FET with specified transconductance.
