Show hintHide hint
Think of what it tells us about the signal's change.
Question 2.
What effect does higher input resistance have on an amplifier's operation?
Show hintHide hint
Consider how the source reacts.
3Question 3.
What is the purpose of determining voltage gain in amplifiers?
- To measure input current

- True
- False
Show hintHide hint
Think about this in terms of load connections.
Question 5.
Calculate the total input capacitance for a circuit with capacitances C1 = 5nF, C2 = 10nF, and a voltage gain of 0.85.
Show hintHide hint
Use the Miller effect formula for total input capacitance.
Question 6.
Explain how varying the collector resistance affects both the input and output resistances of a common collector amplifier and provide an equation to support your explanation.
Show hintHide hint
Consider impedance modeling for both input and outputs.
