Question 1.
What does the parameter β represent in a BJT?
Show hintHide hint
Think about how much larger the collector current is compared to the base current.
Question 2.
What is the main function of trans-conductance (g_m)?
Show hintHide hint
Consider it as a ratio that impacts amplification.
3Question 3.
What does the term 'trans-conductance' refer to?
- The ratio of output voltage to input current
- The ratio of input voltage to output current
- The ratio of output current to input voltage
Show hintHide hint
Think about how changes in voltage affect current outputs.
4Question 4.
True or False: PNP transistors use electrons as majority carriers.
- True
- False
Show hintHide hint
Recall the charge carriers associated with both types of transistors.
Question 5.
Given a BJT with β = 150 and a base current of 5 µA, calculate the collector current.
Show hintHide hint
Apply the formula that relates current gain to collector current.
Question 6.
How would the I-V characteristics of a given BJT change if the temperature is significantly increased?
Show hintHide hint
Consider how temperature affects the behavior of charge carriers in the semiconductor.
