Show hintHide hint
Think about how connected components affect voltage levels.
Question 2.
What is transconductance and why is it important?
Show hintHide hint
Consider its role in amplifier circuits.
3Question 3.
What is the primary purpose of output impedance?
- To measure input voltage
- To determine how output varies with load
- To store charge
Show hintHide hint
Think about the effects of changing the load on circuit performance.
4Question 4.
True or False: Transconductance indicates the efficiency of current to voltage conversion.
- True
- False
Show hintHide hint
Recall how this is often measured in amplifiers.
Question 5.
If you have a common collector circuit with a specified load impedance of 200 ohms and a voltage gain of 2, calculate the required output impedance.
Show hintHide hint
Use the relationship given for voltage gain to find the relation with output impedance.
Question 6.
A transistor has an early voltage of 20V and a collector current of 5mA; calculate the transconductance and the equivalent resistance.
Show hintHide hint
Remember the formulas relating early voltage, collector current, and transconductance!
