4Question 4.
True or False: The input resistance is affected by the output load.
- True
- False
Show hintHide hint
Consider how input resistance is primarily defined.
Question 5.
If a common source amplifier has a transconductance of 3 mA/V and a drain resistor of 10 kΩ, find the voltage gain. Then, what implications does this gain have for small signal amplification?
Show hintHide hint
Use the voltage gain formula and ensure your units align.
Question 6.
Graph the frequency response for a common source amplifier with indicated cutoff frequencies. Discuss how parasitic capacitance at high frequencies modifies performance.
