Challenge Problems
Push your limits with challenges.
Question 1
Given a CE amplifier with an early voltage of 150V, if the beta is expected to be 250, calculate the required resistor values to achieve a stable operating point at 6V DC output voltage when changes in beta vary the current gain to 200.
💡 Hint: Use previous examples to guide your calculations.
Question 2
Discuss the potential effects on amplifier performance if feedback resistors are drastically increased beyond recommended values. What calculations would ensure stable operation?
💡 Hint: Consider how feedback affects amplification and stability.
