Question 1.
Define upper cutoff frequency.
Show hintHide hint
Think about where performance drops off in an amplifier.
Question 2.
What is voltage gain?
Show hintHide hint
Remember the formula for voltage gain.
3Question 3.
What is the upper cutoff frequency in amplifiers?
- Where output voltage equals input voltage
- Where output voltage drops to 70.7% of its maximum
- Where no signal passes
Show hintHide hint
Remember the definition closely tied to performance metrics.
4Question 4.
True or False: A common base amplifier has high input impedance.
- True
- False
Show hintHide hint
Reflect on your understanding of input characteristics.
Question 5.
A common base amplifier has a load capacitance of 100 pF and an output resistance of 10 kΩ. Calculate the upper cutoff frequency.
Show hintHide hint
Remember to convert units properly while plugging into the formula.
Question 6.
If the source resistance is increased and output impedance is given as 2.83 kΩ; analyze how this would affect voltage gain in practical terms.
Show hintHide hint
Think of how source and load resistances interact.
