Challenge Problems
Push your limits with challenges.
Question 1
You have a common emitter amplifier with a beta of 100. If the collector current is measured as 2 mA, calculate the base current and explain what this indicates about biasing.
π‘ Hint: Use the formula for beta to relate the currents.
Question 2
Design a common emitter amplifier circuit that can handle temperature fluctuations of 20Β°C to 30Β°C. Explain your component choices.
π‘ Hint: Consider temperature ratings of components when making choices.
