Question 1.
What is the main characteristic of a CC configuration?
Show hintHide hint
Think about where the connections are made.
Question 2.
Why is high input resistance important?
Show hintHide hint
Consider what happens when one circuit affects another.
3Question 3.
What is the primary benefit of using a CC configuration?
- High Voltage Gain
- Low Output Resistance
- High Input Resistance
Show hintHide hint
Think about how it relates to the input of the amplifier.
4Question 4.
Is it true that cascading a CE stage with a CC stage increases input impedance?
- True
- False
Show hintHide hint
Consider how CC affects the previous configurations.
Question 5.
Design a multi-stage amplifier using both CE and CC configurations. Calculate the total voltage gain if individual gains are 20 and 10.
Show hintHide hint
Remember that gains multiply when stages are cascaded.
Question 6.
If a composite transistor has one stage configured as CE with r_pi=200 Ohm and β=150, and another as CC with negligible output resistance, calculate the increase in input impedance.
Show hintHide hint
Refer to input impedance formulas of cascaded configurations.
