In a fixed bias circuit with a BJT, the nominal beta is 150. What will happen to the collector current if the beta rises to 240 due to an increase in temperature?
💡 Hint: Use the relationship IC = βDC * IB to figure this out.
Evaluate the potential effects on an amplifier's performance if the Q-point shifts to the cutoff region during a temperature test.
💡 Hint: Remember, cutoff means no current flow.
