- True
- False
Show hintHide hint
Think about the comparative gains discussed.
Question 5.
Given a common emitter amplifier, calculate the potential voltage gain if the transconductance is 20 mA/V and the load resistance is 1 kΩ.
Show hintHide hint
Remember the formula for voltage gain.
Question 6.
How would substituting a passive load with an active load affect the thermal stability of the circuit?
Show hintHide hint
Think about feedback and control in your answer.
